MAX4711CSE资料
General DescriptionThe MAX4711/MAX4712/MAX4713 are fault-protected,Rail-to-Rail ®, low-voltage analog switches featuring low on-resistance and guaranteed on-resistance flatness over the specified signal range. Due to the fault protection fea-ture the analog switch input (NO_ or NC_) and output (COM_) pins are not symmetrical. The fault protection fea-ture allows for the analog input to go beyond the plus or minus supplies without the device drawing excessive amounts of current from the analog inputs. When the ana-log inputs are driven beyond the supply rails when the switch is on, it will sense a fault and turn itself off and the analog switch output will be clamped to the same polarity supply as the input signal and will not go beyond the sup-ply rails. This feature protects any electronic circuitry con-nected to the output from excessive voltages present on the analog inputs.The MAX4711/MAX4712/MAX4713 are quad, single-pole/single-throw (SPST) analog switches. The MAX4711has four normally closed switches (NC), the MAX4712 has four normally open switches (NO), and the MAX4713 has two NO and two NC switches. Switching times are less than 125ns for t ON , and less than 80ns for t OFF . These switches operate from a single +2.7V to +11V supply or from dual ±2.7V to ±5.5V supplies. All digital inputs have +0.8V to +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±4.5V to ±5.5V or single +4.5V to +11V supplies.________________________ApplicationsCommunication Systems Battery-Operated Systems Signal Routing Test Equipment Data-AcquisitionIndustrial and Process Control Systems AvionicsRedundant/Backup SystemsFeatures♦Fault-Protected Analog Inputs ♦±12V Fault Protection with Power Off ♦±7V Fault Protection with ±5V Supplies ♦+12V and -7V Fault Protection with +5V Supply ♦+12V and -9V Fault Protection with +3V Supply ♦Fault-Protected Digital Inputs May Exceed V+Supply Rail ♦All Switches Off with Power Off ♦Rail-to-Rail Signal Handling♦Output Clamped to Appropriate Supply Voltages During Fault Condition ♦25Ω(max) R ON at +25°C♦1Ω(max) On-Resistance Match Between Channels ♦Single- and Dual-Supply Operation ♦Pin-Compatible with Industry-Standard MAX391/MAX392/MAX393♦TTL- and CMOS-Compatible Logic Inputs19-1907; Rev 1; 11/03MAX4711/MAX4712/MAX4713Fault-Protected, Low-Voltage, Quad SPST Analog Switches________________________________________________________________Maxim Integrated Products 1Pin Configurations/FunctionalDiagrams/Truth TablesFor price, delivery, and to place orders,please contact Maxim Distribution at 1-888-629-4642,or visit Maxim’s website at .Ordering InformationOrdering Information continued at end of data sheet.Pin Configurations/Functional Diagrams/Truth Tables continued at end of data sheet.Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.M A X 4711/M A X 4712/M A X 4713Fault-Protected, Low-Voltage, Quad SPST Analog SwitchesABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual SuppliesStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

First, they are constructed with two paral-lel FET’s allowing very low on-resistance. Second, they allow signals on the NC_ or NO_ pins that are within or slightly beyond the supply rails to be passed through the switch to the COM terminal, allowing rail-to-rail sig-nal operation. Third, when a signal on NC_ or NO_exceeds the supply rails by about 150mV (a fault con-dition) the voltage on COM_ is limited to the same polarity supply voltage. Operation is identical for both fault polarities.During a fault condition, the NO_ or NC_ input becomes high impedance regardless of the switch state or load resistance. If the switch is on, the COM_output current is supplied from V+ or V- by the clamp FET’s that are connected from COM to each supply.These FET’s can typically source or sink up to 15mA.When power is removed, the fault protection is still in effect. In this case, the NO_ or NC_ terminals are a vir-tual open circuit. The fault can be up to ±12V.The COM_ pins are not fault-protected, they act as nor-mal CMOS switch terminals. If a voltage source is con-nected to any COM_ pin, it should be limited to the supply voltages. Exceeding the supply voltage willcause high currents to flow through the ESD-protected diodes, possibly damaging the device (see Absolute Maximum Ratings ).Pin CompatibilityThese switches have identical pinouts to common non-fault-protected CMOS switches. Care should be exer-cised while considering them for direct replacements in existing printed circuit boards since only the NO_ and NC_ pins of each switch are fault-protected.Internal ConstructionInternal construction is shown in Figure 1, with the ana-log signal paths shown in bold. A single NO switch is shown; the NC configuration is identical except the logic-level translator is inverting. The analog switch is formed by the parallel combination of N-channel FET (N1) and P-channel FET (P1), which are driven on and off simultaneously according to the input fault condition and the logic-level state.Normal OperationTwo comparators continuously compare the voltage on the NO_ (or NC_) pin with V+ and V-. When the signal on NO_ or NC_ is between V+ and V- the switch acts normally, with FETs N1 and P1 turning on and off in response to IN_ signals. The parallel combination of N1 and P1 forms a low-value resistor between NO_ (orFault-Protected, Low-Voltage,10______________________________________________________________________________________NC_) and COM_ so that signals pass equally well in either direction.Positive Fault ConditionWhen the signal on NO_ (or NC_) exceeds V+ by about 150mV, the high-fault comparator output is high, turn-ing off FETs N1 and P1. This makes the NO_ (or NC_)input high impedance regardless of the switch state. If the switch state is “off”, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. If the switch state is “on”, clamp FET P2 is turned on, sourc-ing current from V+ to COM_.Negative Fault ConditionWhen the signal on NO_ (or NC_) exceeds V- by about 150mV, the low-fault comparator output is high, turning off FETs N1 and P1. This makes the NO_ (or NC_) input high impedance regardless of the switch state. If the switch state is “off”, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. If the switch state is “on”, clamp FET N2 is turned on, sinking current from COM_ to V-.Transient Fault Response and RecoveryWhen a fast rise-time or fall-time transient on NC_ or NO_ exceeds V+ or V-, the output (COM_) follows the input to the supply rail with only a few nanoseconds delay. This delay is due to the switch on-resistance and circuit capacitance to ground. When the input transient returns to within the supply rails, however, there is a 700ns output recovery delay time. These values depend on the COM_ output resistance and capaci-tance, and are not production tested or guaranteed.The delays are not dependent on the fault amplitude.Higher COM_ output resistance and capacitance increase recovery times.COM_ and IN_ PinsFETs N2 and P2 can source about ±15mA from V+ or V- to COM_ in the fault condition. Ensure that if the COM_ pin is connected to a low-resistance load, the absolute maximum current rating of 40mA is never exceeded both in normal and fault conditions.MAX4711/MAX4712/MAX4713Fault-Protected, Low-Voltage, Quad SPST Analog Switches______________________________________________________________________________________11Figure 1. Block DiagramM A X 4711/M A X 4712/M A X 4713The COM_ pins do not have fault protection. Reverse ESD-protection diodes are internally connected between COM_, and V+ and V-. If a signal on COM_exceeds V+ or V- by more than a diode drop, one of these diodes will conduct. The IN_ pin can exceed the positive supply voltage, but they can go below the neg-ative supply by only a diode drop. The maximum volt-age on these pins is 12V if operating from a single supply, regardless of the supply voltage (including 0volts), and if operating from dual supplies, the maxi-mum voltage is (V- + 12V).Fault-Protection Voltage and Power OffThe maximum fault voltage on the NC_ or NO_ pins is ±12V with power off.IN_ Logic-Level ThresholdsThe logic-level thresholds are CMOS and TTL compati-ble when using ±4.5V to ±5.5V or single +4.5V to +11V supplies. When using a +2.7V supply, the logic thresh-olds are V IH = 2.0V and V IL = 0.6V.Dual SuppliesThe MAX4711/MAX4712/MAX4713 operate with bipolar supplies between ±2.7V and ±5.5V. The V+ and V-supplies need not be symmetrical, but their difference should not exceed 11V.Single SupplyThe MAX4711/MAX4712/MAX4713 operate from a sin-gle supply between +2.7V and +11V when V- is con-nected to GND.Chip InformationTRANSISTOR COUNT: 463Fault-Protected, Low-Voltage, Quad SPST Analog SwitchesPin Configurations/Functional Diagrams/Truth Tables (continued)Ordering Information (continued)MAX4711/MAX4712/MAX4713Fault-Protected, Low-Voltage, Quad SPST Analog Switches______________________________________________________________________________________13Test Circuits/Timing DiagramsFigure 2.

The MAX16141 is a diode controller and protection device that protects systems against fault conditions such as reverse current, overcurrent, input overvoltage/undervoltage, short circuit and over temperature. The MAX16141 EV kit’s undervoltage and overvoltage thresholds are configured to 8.6V and 36.2V, respectively.The MAX16141 EV kit comes with the MAX16141ATE+ (16-TQFN) installed and is configured to operate normally between 8.6V and 36.2V. Under normal operation, the output follows the input. The output will shut down (0V) when the input is risen above 36.2V (i.e., 37V or higher), or drop below 8.6V (i.e., 7V or lower). The output will also shut down when the load at the output goes above 5A, or in an event of a short circuit at the output.SHDNThe MAX16141 EV kit provides a jumper (JU1) to enable or disable the MAX16141. Refer to Table 1 for JU1 jumper settings.SLEEPThe MAX16141 EV kit provides a jumper (JU2) to pullup the active-low sleep mode input of the MAX16141. Refer to Table 2 for JU2 jumper settings.GATE SnubberFor applications that require slower gate rise time than what is achieved using a resistor from GRC to GND, an external resistor and capacitor (snubber) network can be added from GATE to GND. However, the recommended value is 1k Ω resistor in series with a 10nF cap.The MAX16141 EV Kit provides a jumper (JU3) to add or remove the snubber at the power MOSFET gates. Refer to Table 3 for jumper settings.Overvoltage ProtectionThe MAX16141 EV kit shuts down the output when the input voltage exceeds the upper input voltage limit set by resistors R11 and R9 between the TERM and OVSET pins of the MAX16141.

iMaster NCE-Fabric 01 产品说明书
iMaster NCE-Fabric BrochureiMaster NCE-Fabric 01Product Description Architecture and Key ComponentsWith the advent of the 5G and cloud era, innovativeservices such as VR/AR, live broadcast, and unmanneddriving are emerging. The ever-expanding amounts ofdata and increasingly complex cybersecurity threatsare changing the technology landscape at breakneckspeed. The development of science and technology isnarrowing down the gap between users and serviceproviders, and widely distributed applications and datalead to the rise of distributed computing models. In thiscase, it is important to adopt a radically new approachto networking. The current rigid and largely manuallifecycle management approach is no longer sustainablefor deploying, maintaining, and updating networks, and iMaster NCE-Fabric is developed based on the cloud-native architecture. It adopts the service-oriented module design and supports distributed virtualization deployment. It consists of the following modules: common services, management+control+analysis, scenario-based apps, and open APIs.• Common service module: provide basic network services such as alarms and logs and product engineering capabilities such as geographic redundancy and backup.• Management, control, and analysis module: provides network management, service automation, analysis, and prediction capabilities.• Scenario-based app module: provides service capabilities such as O&M services for different business scenarios.• Open API module: provides northbound APIs to quickly interconnect and integrate with third-party applications or other management and control systems.it cannot scale to meet the growing complexity. For an organization to flourish in the digital economy, the data center network needs to adapt quickly to changing business requirements or intent.HUAWEI iMaster NCE-Fabric, an important part of Huawei CloudFabric Solution, is a network automation and intelligence platform that integrates management, control, analysis, and AI functions. It efficiently translates business intent into physical networks, provides capabilities such as full-lifecycle simplified deployment and intelligent fault remediation, and redefines service provisioning and O&M of data centernetworks.iMaster NCE-Fabric 02High lights Key FeaturesZero-Waiting Service Deployment Through Graphical DraggingReduces the workload of O&M personnel, improves the work efficiency of O&M personnel, and shortens the service deployment and rollout time.Zero-Error Configuration Change Through Simulation VerificationEstablishes a technical mechanism to prevent problems caused by manual misoperations, improving work efficiency and security productivity.Zero-Interruption Intelligent O&M Through Proactive Prediction (“1-3-5 Troubleshooting")Prevents network quality deterioration and detects faults before they occur, minimizing faults. In case of a fault, it can be quickly located and resolved, implementing easy O&M.iMaster NCE-Fabric provides one-click ZTP deployment and flexible planning-based deployment for the physical underlay network to meet automatic networking requirements and implement fast network infrastructure construction, upgrade, and capacity expansion. iMaster NCE-Fabric provides a simplified drag and drop network design and automatic provisioning process for logical overlay networks. The provisioning efficiency is three times the industry average, facilitating service provisioning in minutes.5IJSE QBSUZ *5 044 "QQTResource Management Switch Router FWO&M service NETCONF RESTFUL OPENFLOW RESTFUL MTOSI XML Syslog SNMP RESTCONF Root cause Predictive maintenanceHealth status Underlay service SNMP System Monitoring Geographic RedundancyInstallation and deploymentSecurityLogLicense Service provisioning NE configuration NE maintenance NE upgrade Service template Service maintenance Intent-driven Performance management Tenant management ZTP Resource visualization Fault simulation SFC Path detection Resource prediction Impact analysis Alarm RCA SLA analysis Health prediction Knowledge graph Alarm Inventory resource Topology Resource pool Basic ServiceSBINetwork infrastructure Open API Build-in APP Automated E2E Network DeploymentiMaster NCE-Fabric 03Intent-based Network DeploymentTraditionally, services are transferred from the service department to the network department using work orders. The network department designs the network plan based on the work orders and deploys the services. This process requires a large amount of communication, which is time-consuming and may cause requirements missing. iMaster NCE-Fabric introduces AI to implement intent-based networking in three steps:• Understands and translates the service intent entered by administrators into network intent.• Provides multiple preferred network models and deployment solutions based on AI model calculation and configuration plane simulation verification.• Converts a network deployment solution into NE configurations and automatically delivers the configurations to network devices.Change Risk AssessmentNearly 40% of faults on a network are caused by human errors, such as logical vulnerabilities in network design, deviation from administrator intent, and misoperations. Risk evaluation of network changes and policy adjustment consumes a large amount of human resources.iMaster NCE-Fabric provides a simulation verification module. Based on the live network configuration, topology, and resources, iMaster NCE-Fabric uses network modeling and formal verification algorithms to check whether the remaining network resources are sufficient, displays detailed connectivity relationships, and analyzes the impact of configuration changes on the original services. Therefore, network engineers can use iMaster NCE-Fabric to pre-evaluate change risks, radically resolve human-caused problems such as design logic vulnerabilities, and ensure zero network configuration errors.On-demand Deployment of the Container NetworkWith the rapid development of container technology, containers are favored by users because of their lightweight, easy-to-deploy, and easy-to-port features. Container services are deployed in more data centers. However, the network where containers are running needs to be pre-deployed and is separated from the traditional VM or BM network, which lowers the deployment and O&M efficiency.iMaster NCE-Fabric flexibly interconnects with the container orchestration system through plug-ins to implement on-demandiMaster NCE-Fabric04iMaster NCE-Fabric 05deployment and unified management of container networks, improving O&M efficiency by more than 30%.FusionStageiMaster NCE-Fabric06"1-3-5" TroubleshootingData centers are service support centers, and more importantly, value creation centers. For 98% enterprises, if their services are interrupted for 1 hour, the loss will exceed US$100,000. Customers have no tolerance for network interruptions. Currently, network O&M is performed mainly manually. Once a fault occurs on the network, it is difficult and time-consuming to locate the fault manually, which seriously affects customers' service continuity.iMaster NCE-Fabric uses the Telemetry technology to collect data from the management plane, forwarding plane, and data plane on the entire network in real time, and detects faults in minutes from the service experience perspective. So far, Huawei has accumulated the O&M experience for more than 30 years and is very familiar with network fault scenarios of more than 7,800 data center customers. Based on these, iMaster NCE-Fabric has summarized 75 typical faults of 7 types and uses AI algorithms to build a network knowledge graph. Through continuous efforts in fault drills in Huawei, we can locate most faults within 3 minutes. iMaster NCE-Fabric supports intent-based fault remediation and intelligently analyzes fault impacts. It recommends emergency plans and can rectify typical faults within 5 work Health AssessmentiMaster NCE-Fabric comprehensively assesses network health based on the physical environment, resources, protocols, overlay network, and service models, and provides assessment analysis conclusions from the service experience perspective. The O&M personnel can export the assessment report in one-click mode and easily manage network health.iMaster NCE-Fabric supports predictive maintenance. It detects network exceptions based on the dynamic baseline, intelligently predicts the optical module fault rate and port traffic, and generates warnings in advance. Compared with the traditional passive O&M, it can proactively identify network exceptions before they occur.iMaster NCE-Fabric 07NE management and controlNetwork service provisioning • NE fault, configuration, accounting, performance, security (FCAPS) and basic network configuration • iMaster NCE-Fabric can interconnect with the mainstream cloud platformOpenStack, container orchestration platform, or third-party applications. The cloud platform or third-party applications invoke the standard APIs to provision network services.• iMaster NCE-Fabric independently provisions IPv4 or IPv6 network services to implement automatic network deployment.• Supports device go-online through ZTP and automatic faulty device replacement.• Automatically identifies and manages network devices.• Supports traffic diversion to third-party firewalls and load balancers.• Supports microsegmentation.• Supports role-based access control.• Supports local or remote authentication (RADIUS, AD, and LDAP authentication).• Supports logical resource monitoring.• Supports visibility of the application, logical, and physical network topologies.

MAX202CSE中文资料
General DescriptionThe MAX200–MAX211/MAX213 transceivers are designed for RS-232 and V.28 communication inter-faces where ±12V supplies are not available. On-board charge pumps convert the +5V input to the ±10V need-ed for RS-232 output levels. The MAX201 and MAX209operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter.The MAX200–MAX211/MAX213 drivers and receivers meet all EIA/TIA-232E and CCITT V.28 specifications at a data rate of 20kbps. The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification.The 5µW shutdown mode of the MAX200, MAX205,MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shut-down and an active-high receiver enable control. Two receivers of the MAX213 are active, allowing ring indica-tor (RI) to be monitored easily using only 75µW power.The MAX211 and MAX213 are available in a 28-pin wide small-outline (SO) package and a 28-pin shrink small-outline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is now avail-able in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components,and are recommended for applications with limited circuit board space.ApplicationsComputersLaptops, Palmtops, Notebooks Battery-Powered Equipment Hand-Held Equipment Next-Generation Device Features ♦For Low-Cost Applications:MAX221E: ±15kV ESD-Protected, +5V, 1µA, Single RS-232 Transceiver with AutoShutdown™♦For Low-Voltage and Space-Constrained Applications:MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: ±15kV ESD-Protected, Down to 10nA,+3.0V to +5.5V, Up to 1Mbps, True RS-232Transceivers (MAX3246E Available in UCSP™Package)♦For Space-Constrained Applications:MAX3228E/MAX3229E: ±15kV ESD-Protected,+2.5V to +5.5V, RS-232 Transceivers in UCSP ♦For Low-Voltage or Data Cable Applications:MAX3380E/MAX3381E: +2.35V TO +5.5V, 1µA,2Tx/2Rx RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins ♦For Low-Power Applications:MAX3224E–MAX3227E/MAX3244E/MAX3245E:±15kV ESD-Protected, 1µA, 1Mbps, +3.0V to+5.5V, RS-232 Transceivers with AutoShutdown Plus™MAX200–MAX211/MAX213+5V , RS-232 Transceivers with 0.1µF External Capacitors ________________________________________________________________Maxim Integrated Products 119-0065; Rev 6; 10/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering Information appears at end of data sheetAutoShutdown, AutoShutdown Plus, and UCSP are trademarks of Maxim Integrated Products, Inc.MAX200–MAX211/MAX213+5V , RS-232 Transceiverswith 0.1µF External Capacitors______________________________________________________________________________________19Ordering Information*Contact factory for dice specifications.M A X 200–M A X 211/M A X 213+5V , RS-232 Transceiverswith 0.1µF External Capacitors Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.

The MIC47100 can source 1A of output current while only requiring a 1µF ceramic output capacitor for stability.The MIC47100 regulator is fully protected from damage dueto fault conditions, offering linear current limiting and thermal shutdown.Bias Supply VoltageV BIAS, requiring relatively light current, provides powerto the control portion of the MIC47100. Bypassing on the bias pin is recommended to improve performanceof the regulator during line and load transients. Small ceramic capacitors from V BIAS-to-ground help reduce high frequency noise from being injected into the control circuitry from the bias rail and are good design practice.Input Supply VoltageV IN provides the supply to power the LDO. The minimum input voltage is 1V, allowing conversion from low voltage supplies.Output CapacitorThe MIC47100 requires an output capacitor of 1µF or greater to maintain stability. The design is optimizedfor use with low-ESR ceramic chip capacitors. High ESR capacitors may cause high frequency oscillation. The output capacitor can be increased, but performance has been optimized for a 1µF ceramic output capacitor and does not improve significantly with larger capacitance.X7R/X5R dielectric-type ceramic capacitors are recommended because of their temperature performance. X7R-type capacitors change capacitance by 15% over their operating temperature range and are the most stable type of ceramic capacitors. Z5U and Y5V dielectric capacitors change value by as much as 50% and 60%, respectively, over their operating temperature ranges. To use a ceramic chip capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range.Input CapacitorThe MIC47100 is a high-performance, high bandwidth device. Therefore, it requires a well-bypassed input supply for optimal performance. A 1µF capacitor is required from the input to ground to provide stability. Low-ESR ceramic capacitors provide optimal performance at a minimum of space. Additional high-frequency capacitors, such as small-valued NPO dielectric-type capacitors, help filter out high-frequency noise and are good practice in any RF-based circuit.Minimum Load CurrentThe MIC47100, unlike most other regulators, does not require a minimum load to maintain output voltage regulation.Adjustable Regulator DesignThe MIC47100 adjustable version allows programming the output voltage anywhere between 0.8V and 2.0V. Two resistors are used. The R1 resistor value between V OUT and the adjust pin should not exceed 10kΩ. Larger values can cause instability.R2 connects between the adjust pin and ground. The resistor values are calculated by:⎟⎟⎠⎞⎜⎜⎝⎛−×=10.7VR2R1OUTWhere V OUT is the desired output voltage.Enable/ShutdownThe MIC47100 comes with a single active-high enable pin that allows the regulator to be disabled. Forcing the enable pin low disables the regulator and sends it into a “zero” off-mode-current state. In this state, current consumed by the regulator goes nearly to zero. Forcing the enable pin high enables the output voltage. The active-high enable pin uses CMOS technology and the enable pin cannot be left floating;a floating enable pin may cause an indeterminate state on the output.Thermal ConsiderationsThe MIC47100 is designed to provide 1A of continuous current in a very small package. Maximum ambient operating temperature can be calculated based on the output current and the voltage drop across the part. Given that the input voltage is 1.8V, the output voltage is 1.2V and the output current is1A. The actual power dissipation of the regulator circuit can be determined using the equation:P D = (V IN – V OUT1) I OUT + V BIAS I GNDBecause this device is CMOS, the ground current is insignificant for power dissipation and can be ignored for this calculation.P D = (1.8V – 1.2V) × 1AP D = 0.6WTo determine the maximum ambient operating temperature of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation:P D(MAX) =T J(max) = 125°C, the maximum junction temperature of the die θJA thermal resistance = 90°C/W.The table below shows junction-to-ambient thermal resistance for the MIC47100 in the MLF ® package.PackageθJA Recommended MinimumFootprintθJC 8-pin 2mm x 2mmMLF ®90°C/W 2°C/WThermal ResistanceSubstituting P D for P D(max) and solving for the ambientoperating temperature will give the maximum operating conditions for the regulator circuit. The junction-to-ambient thermal resistance for the minimum footprint is 90°C/W.The maximum power dissipation must not be exceeded for proper operation.For example, when operating the MIC47100-1.2YML at an input voltage of 1.8V and a 1A load with a minimum footprint layout, the maximum ambient operating temperature T A can be determined as follows:C T W C T C W A A °=°−°=71)/90()125(6.0Therefore, a 1.2V application with 1A of output current can accept an ambient operating temperature of 71°C in a 2mm x 2mm MLF ® package.

For lead (Pb)-free solder paste like Sn(3.0-4.0)Ag(0.5-0.9)Cu,there are two standard reflow profiles: Ramp-Soak-Spike (RSS) and Ramp-To-Spike (RTS). The Ramp-Soak-Spike profile was developed primarily for reflow ovens heated by infrared radiation. With widespread use of forced convection reflow ovens the Ramp-To-Spike profile is used increasingly. Shown below in fig-ure 2 is VISHAY's recommended profiles for use with the TFBS4711 transceivers. For more details please refer to Application note: SMD Assembly Instruction.Wave SolderingFor TFDUxxxx and TFBSxxxx transceiver devices wave soldering is not recommended.Manual SolderingManual soldering is the standard method for lab use.However, for a production process it cannot be rec-ommended because the risk of damage is highly dependent on the experience of the operator. Never-theless, we added a chapter to the above mentioned application note, describing manual soldering and desoldering.StorageThe storage and drying processes for all VISHAY transceivers (TFDUxxxx and TFBSxxx) are equiva-lent to MSL4.The data for the drying procedure is given on labels on the packing and also in the application note "Taping, Labeling, Storage and Packing"(/docs/82601/82601.pdf).Figure 1. Recommended Solder Profile for Sn/Pb solderingFigure 2. Solder Profile, RSS Recommendation Document Number 82633Recommended Circuit DiagramOperated at a clean low impedance power supply the TFBS4711 needs no additional external components when the internal current control is used. For reducing the IRED drive current for low power applications with reduced range an additional resistor can be used to connect the IRE D to the separate power supply.Depending on the entire system design and board layout, additional components may be required. (see figure 3).Worst-case conditions are test set-ups with long cables to power supplies. In such a case capacitors are necessary to compensate the effect of the cable inductance. In case of small applications as e.g.mobile phones where the power supply is close to the transceiver big capacitors are normally not neces-sary. The capacitor C1 is buffering the supply voltage and eliminates the inductance of the power supply line. This one should be a small ceramic version or other fast capacitor to guarantee the fast rise time of the IRE D current. The resistor R1 is optional for reducing the IRED drive current.Vishay transceivers integrate a sensitive receiver and a built-in power driver. The combination of both needs a careful circuit board layout. The use of thin, long,resistive and inductive wiring should be avoided. The inputs (TXD, SD) and the output RXD should be directly (DC) coupled to the I/O circuitThe capacitor C2 combined with the resistor R2 is the low pass filter for smoothing the supply voltage when noisy supply voltage is used or pick-up via the wiring is expected.R2, C1 and C2 are optional and dependent on the quality of the supply voltage V CCX and injected noise.An unstable power supply with dropping voltage dur-ing transmission may reduce the sensitivity (and transmission range) of the transceiver.The placement of these parts is critical. It is strongly recommended to position C2 as close as possible to the transceiver power supply pins.In any case, when connecting the described circuit to the power supply, low impedance wiring should be used.When extended wiring is used the inductance of the power supply can cause dynamically a voltage drop at V CC2. Often some power supplies are not to follow the fast current rise time. In that case another 10 µF capacitor at V CC2 will be helpful.The recommended components in table 1 are for test set-upsKeep in mind that basic RF - design rules for circuit design should be taken into account. E specially longer signal lines should not be used without termi-nation.

General DescriptionThe MAX4711/MAX4712/MAX4713 are fault-protected,Rail-to-Rail ®, low-voltage analog switches featuring low on-resistance and guaranteed on-resistance flatness over the specified signal range. Due to the fault protection fea-ture the analog switch input (NO_ or NC_) and output (COM_) pins are not symmetrical. The fault protection fea-ture allows for the analog input to go beyond the plus or minus supplies without the device drawing excessive amounts of current from the analog inputs. When the ana-log inputs are driven beyond the supply rails when the switch is on, it will sense a fault and turn itself off and the analog switch output will be clamped to the same polarity supply as the input signal and will not go beyond the sup-ply rails. This feature protects any electronic circuitry con-nected to the output from excessive voltages present on the analog inputs.The MAX4711/MAX4712/MAX4713 are quad, single-pole/single-throw (SPST) analog switches. The MAX4711has four normally closed switches (NC), the MAX4712 has four normally open switches (NO), and the MAX4713 has two NO and two NC switches. Switching times are less than 125ns for t ON , and less than 80ns for t OFF . These switches operate from a single +2.7V to +11V supply or from dual ±2.7V to ±5.5V supplies. All digital inputs have +0.8V to +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±4.5V to ±5.5V or single +4.5V to +11V supplies.________________________ApplicationsCommunication Systems Battery-Operated Systems Signal Routing Test Equipment Data-AcquisitionIndustrial and Process Control Systems AvionicsRedundant/Backup SystemsFeatures♦Fault-Protected Analog Inputs ♦±12V Fault Protection with Power Off ♦±7V Fault Protection with ±5V Supplies ♦+12V and -7V Fault Protection with +5V Supply ♦+12V and -9V Fault Protection with +3V Supply ♦Fault-Protected Digital Inputs May Exceed V+Supply Rail ♦All Switches Off with Power Off ♦Rail-to-Rail Signal Handling♦Output Clamped to Appropriate Supply Voltages During Fault Condition ♦25Ω(max) R ON at +25°C♦1Ω(max) On-Resistance Match Between Channels ♦Single- and Dual-Supply Operation ♦Pin-Compatible with Industry-Standard MAX391/MAX392/MAX393♦TTL- and CMOS-Compatible Logic Inputs19-1907; Rev 1; 11/03MAX4711/MAX4712/MAX4713Fault-Protected, Low-Voltage, Quad SPST Analog Switches________________________________________________________________Maxim Integrated Products 1Pin Configurations/FunctionalDiagrams/Truth TablesFor price, delivery, and to place orders,please contact Maxim Distribution at 1-888-629-4642,or visit Maxim’s website at .Ordering InformationOrdering Information continued at end of data sheet.Pin Configurations/Functional Diagrams/Truth Tables continued at end of data sheet.Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.M A X 4711/M A X 4712/M A X 4713Fault-Protected, Low-Voltage, Quad SPST Analog SwitchesABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual SuppliesStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

First, they are constructed with two paral-lel FET’s allowing very low on-resistance. Second, they allow signals on the NC_ or NO_ pins that are within or slightly beyond the supply rails to be passed through the switch to the COM terminal, allowing rail-to-rail sig-nal operation. Third, when a signal on NC_ or NO_exceeds the supply rails by about 150mV (a fault con-dition) the voltage on COM_ is limited to the same polarity supply voltage. Operation is identical for both fault polarities.During a fault condition, the NO_ or NC_ input becomes high impedance regardless of the switch state or load resistance. If the switch is on, the COM_output current is supplied from V+ or V- by the clamp FET’s that are connected from COM to each supply.These FET’s can typically source or sink up to 15mA.When power is removed, the fault protection is still in effect. In this case, the NO_ or NC_ terminals are a vir-tual open circuit. The fault can be up to ±12V.The COM_ pins are not fault-protected, they act as nor-mal CMOS switch terminals. If a voltage source is con-nected to any COM_ pin, it should be limited to the supply voltages. Exceeding the supply voltage willcause high currents to flow through the ESD-protected diodes, possibly damaging the device (see Absolute Maximum Ratings ).Pin CompatibilityThese switches have identical pinouts to common non-fault-protected CMOS switches. Care should be exer-cised while considering them for direct replacements in existing printed circuit boards since only the NO_ and NC_ pins of each switch are fault-protected.Internal ConstructionInternal construction is shown in Figure 1, with the ana-log signal paths shown in bold. A single NO switch is shown; the NC configuration is identical except the logic-level translator is inverting. The analog switch is formed by the parallel combination of N-channel FET (N1) and P-channel FET (P1), which are driven on and off simultaneously according to the input fault condition and the logic-level state.Normal OperationTwo comparators continuously compare the voltage on the NO_ (or NC_) pin with V+ and V-. When the signal on NO_ or NC_ is between V+ and V- the switch acts normally, with FETs N1 and P1 turning on and off in response to IN_ signals. The parallel combination of N1 and P1 forms a low-value resistor between NO_ (orFault-Protected, Low-Voltage,10______________________________________________________________________________________NC_) and COM_ so that signals pass equally well in either direction.Positive Fault ConditionWhen the signal on NO_ (or NC_) exceeds V+ by about 150mV, the high-fault comparator output is high, turn-ing off FETs N1 and P1. This makes the NO_ (or NC_)input high impedance regardless of the switch state. If the switch state is “off”, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. If the switch state is “on”, clamp FET P2 is turned on, sourc-ing current from V+ to COM_.Negative Fault ConditionWhen the signal on NO_ (or NC_) exceeds V- by about 150mV, the low-fault comparator output is high, turning off FETs N1 and P1. This makes the NO_ (or NC_) input high impedance regardless of the switch state. If the switch state is “off”, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. If the switch state is “on”, clamp FET N2 is turned on, sinking current from COM_ to V-.Transient Fault Response and RecoveryWhen a fast rise-time or fall-time transient on NC_ or NO_ exceeds V+ or V-, the output (COM_) follows the input to the supply rail with only a few nanoseconds delay. This delay is due to the switch on-resistance and circuit capacitance to ground. When the input transient returns to within the supply rails, however, there is a 700ns output recovery delay time. These values depend on the COM_ output resistance and capaci-tance, and are not production tested or guaranteed.The delays are not dependent on the fault amplitude.Higher COM_ output resistance and capacitance increase recovery times.COM_ and IN_ PinsFETs N2 and P2 can source about ±15mA from V+ or V- to COM_ in the fault condition. Ensure that if the COM_ pin is connected to a low-resistance load, the absolute maximum current rating of 40mA is never exceeded both in normal and fault conditions.MAX4711/MAX4712/MAX4713Fault-Protected, Low-Voltage, Quad SPST Analog Switches______________________________________________________________________________________11Figure 1. Block DiagramM A X 4711/M A X 4712/M A X 4713The COM_ pins do not have fault protection. Reverse ESD-protection diodes are internally connected between COM_, and V+ and V-. If a signal on COM_exceeds V+ or V- by more than a diode drop, one of these diodes will conduct. The IN_ pin can exceed the positive supply voltage, but they can go below the neg-ative supply by only a diode drop. The maximum volt-age on these pins is 12V if operating from a single supply, regardless of the supply voltage (including 0volts), and if operating from dual supplies, the maxi-mum voltage is (V- + 12V).Fault-Protection Voltage and Power OffThe maximum fault voltage on the NC_ or NO_ pins is ±12V with power off.IN_ Logic-Level ThresholdsThe logic-level thresholds are CMOS and TTL compati-ble when using ±4.5V to ±5.5V or single +4.5V to +11V supplies. When using a +2.7V supply, the logic thresh-olds are V IH = 2.0V and V IL = 0.6V.Dual SuppliesThe MAX4711/MAX4712/MAX4713 operate with bipolar supplies between ±2.7V and ±5.5V. The V+ and V-supplies need not be symmetrical, but their difference should not exceed 11V.Single SupplyThe MAX4711/MAX4712/MAX4713 operate from a sin-gle supply between +2.7V and +11V when V- is con-nected to GND.Chip InformationTRANSISTOR COUNT: 463Fault-Protected, Low-Voltage, Quad SPST Analog SwitchesPin Configurations/Functional Diagrams/Truth Tables (continued)Ordering Information (continued)MAX4711/MAX4712/MAX4713Fault-Protected, Low-Voltage, Quad SPST Analog Switches______________________________________________________________________________________13Test Circuits/Timing DiagramsFigure 2.
