MAX4533CAP中文资料

General DescriptionThe MAX4533 quad, single-pole/double-throw (SPDT),fault-protected analog switch is pin-compatible with the industry-standard MAX333 and MAX333A. The MAX4533features fault-protected inputs and Rail-to-Rail ®signal handling. The normally open (NO_ ) and normally closed (NC_ ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±40V with power off.During a fault condition, NO_ and NC_ become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output (COM_)clamps to the appropriate polarity supply rail and pro-vides up to ±10mA of load current. This ensures unam-biguous rail-to-rail outputs when a fault occurs.The MAX4533 operates from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175Ωmax and is matched between switches to 10Ωmax. The off-leakage current is only 0.5nA at T A =+25°C and 10nA at T A =+85°C.ApplicationsRedundant/Backup Systems Portable Instruments Test EquipmentData-Acquisition Communications Systems SystemsIndustrial and Process ControlAvionics SystemsFeatureso Rail-to-Rail Signal Handlingo ±40V Fault Protection with Power Off±25V Fault Protection with ±15V Supplies o All Switches Off with Power Offo No Power-Supply Sequencing Required During Power-Up or Power-Down o Output Clamped to Appropriate Supply Voltage During Fault Condition—No Transition Glitch o 1k Ω(typ) Output Clamp Resistance During Overvoltage o 175Ω(max) Signal Paths with ±15V Supplies o 20ns (typ) Fault Response Time o ±4.5V to ±18V Dual Supplies +9V to +36V Single Supplyo Pin-Compatible with Industry-Standard MAX333/MAX333Ao TTL/CMOS-Compatible Logic Inputs with ±15V or Single +9V to +15V SuppliesMAX4533†Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch________________________________________________________________Maxim Integrated Products 1Typical Operating Circuit19-1452; Rev 1; 10/99Pin Configuration/Functional DiagramOrdering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.†Patent PendingFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog SwitchABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —Dual Supplies(V+ = +15V, V- = -15V, T A = T MIN to T MAX , unless otherwise noted.

Traditional fault-pro-tected switches are constructed using three-series CMOS devices. This combination produces good fault protection but fairly high on-resistance when the signals are within about 3V of each supply rail. These series devices are not capable of handling signals up to the power-supply rails.The MAX4533 differs considerably from traditional fault-protected switches, with three advantages. First, it is constructed with two parallel FETs, allowing very low on-resistance when the switch is on. Second, they allow signals on the NC_ or NO_ pins that are within or slightlybeyond the supply rails to be passed through the switch to the COM_ terminal, allowing rail-to-rail signal opera-tion. Third, when a signal on NC_ or NO_ exceeds the supply rails by about 150mV (a fault condition), the volt-age on COM_ is limited to the appropriate polarity sup-ply voltage. Operation is identical for both fault polarities. The fault-protection extends to ±25V with power on and ±40V with power off.The MAX4533 has a parallel N-channel and P-channel MOSFET switch configuration with input voltage sensors.The simplified internal structure is shown in Figure 1. The parallel N1 and P1 MOSFETs form the switch element.N3 and P3 are sensor elements to sample the input volt-age and compare it against the power-supply rails.*When the voltage on NO_ or NC_ does not exceed V+ or V-, NO_ (or NC_) and COM_ pins are bidirectional.During normal operation of a conducting channel, N1and P1 remain on with a typical 125Ωon-resistance between NO_ (or NC_) and COM_. If the input voltage exceeds either supply rail by about 150mV, the parallel combination switches (N1, P1) are forced off through the driver and sensing circuitries. At the same time, the output (COM_ ) is clamped to the appropriate supply rail by the clamp circuitries (N2, P2). Two clamp circuits limit the output voltage to the supply voltages.For simplicity, Figure 1 shows only one side of the SPDT switch configuration. The complete circuit is composed of two channels with their outputs connected.Normal OperationTwo comparators continuously compare the voltage on the NO_ (or NC_ ) pin with V+ and V- supply voltages.When the signal on NO_ (or NC_ ) is between V+ and V-, the switch behaves normally, with FETs N1 and P1turning on and off in response to NO_ (or NC_) signals (Figure 1). For any voltage between the supply rails,the switch is bidirectional; therefore, COM_ and NC_(or NO_ ) are interchangeable. Only NO_ and NC_ can be exposed to overvoltages beyond the supply range and within the specified breakdown limits of the device.Fault ConditionThe MAX4533 protects devices connected to its output (COM_) through its unique fault-protection circuitry.When the input voltage is raised above either supply rail, the internal sense and comparator circuitries (N3and N-channel driver or P3 and P-channel driver) dis-connect the output (COM_) from the input (Figure 1).If the switch driven above the supply rail has an on state, the clamp circuitries (N2 or P2) connect the out-put to the appropriate supply rail. Table 1 summarizes the MAX4533’s operation under normal and fault condi-tions. Row 5 shows a negative fault condition when the supplies are on. It shows that with supplies of ±15V, if the input voltage is between -15V and -25V, the output (COM_) clamps to the negative supply rail of -15V.With this technique, the SPDT switch is capable of with-standing a worse-case condition of opposite fault polar-ities at its inputs.Transient Fault ConditionWhen a fast rising or falling transient on NO_ (or NC_)exceeds V+ or V-, the output (COM_) follows the input (IN_) to the supply rail by only a few nanoseconds. This delay is due to the switch on-resistance and circuit capacitance to ground. However, when the input tran-sient returns to within the supply rails there is a longer recovery time. For positive faults, the recovery time is typically 2.5µs. For negative faults, the recovery time is typically 1.3µs. These values depend on the COM_ out-put resistance and capacitance. The delays are not dependent on the fault amplitude. Higher COM_ output resistance and capacitance increase the recovery times.Fault Protection, Voltage, and Power OffThe maximum fault voltage on the NO_ or NC_ pins is ±40V from ground when the power is off. With ±15V sup-ply voltages, the highest voltage on NO_ (or NC_) can be +25V, and the lowest voltage on NO_ (or NC_) can be -25V. Exceeding these limits can damage the chip.IN_ Logic-Level ThresholdsThe logic-level thresholds are TTL/CMOS-compatible when V+ is +15V. Raising V+ increases the threshold slightly; when V+ reaches +25V, the level threshold is 2.8V—higher than the TTL output high-level minimum of 2.4V, but still compatible with CMOS outputs (see the Typical Operating Characteristics ).Increasing V- has no effect on the logic-level thresh-olds, but it does increase the gate-drive voltage to the signal FETs, reducing their on-resistance.MAX4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch_______________________________________________________________________________________9Figure 1. Simplified Internal StructureFailure ModesThe MAX4533 is not a lightning arrester or surge pro-tector. Exceeding the fault-protection voltage limits on NO_ or NC_, even for very short periods, can cause the device to fail.Applications InformationGroundThere is no connection between the analog signal paths and GND. The analog signal paths consist of an N-channel and P-channel MOSFET with their sources and drains paralleled and their gates driven out of phase to V+ and V- by the logic-level translators.V+ and GND power the internal logic and logic-level translators and set the input logic thresholds. The logic-level translators convert the logic levels to switched V+and V- signals to drive the gates of the switches. Thisdrive signal is the only connection between the power supplies and the analog signals. GND, IN_, and COM_have ESD protection diodes to V+ and V-.Supply Current ReductionWhen the logic signals are driven rail-to-rail from 0 to +12V or -15V to +15V, the supply current reduces to approximately half of the supply current when the logic input levels are at 0 to 5V.Power SuppliesThe MAX4533 operates with bipolar supplies between ±4.5V and ±18V. The V+ and V- supplies need not be symmetrical, but their difference can not exceed the absolute maximum rating of +44V. The MAX4533 oper-ates from a single supply between +9V and +36V when V- is connected to GND.M A X 4533Quad, Rail-to-Rail, Fault-Protected,SPDT Analog Switch 10______________________________________________________________________________________Table 1.

General DescriptionDevices in the MAX3483E family (MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E) are ±15kV ESD-protected, +3.3V, low-power transceivers for RS-485 and RS-422 communications. Each device con-tains one driver and one receiver. The MAX3483E and MAX3488E feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly termi-nated cables, allowing error-free data transmission at data rates up to 250kbps. The partially slew-rate-limited MAX3486E transmits up to 2.5Mbps. The MAX3485E,MAX3490E, and MAX3491E transmit at up to 12Mbps.All devices feature enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model.Drivers are short-circuit current limited and are protect-ed against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if both inputs are open circuit.The MAX3488E, MAX3490E, and MAX3491E feature full-duplex communication, while the MAX3483E,MAX3485E, and MAX3486E are designed for half-duplex communication.ApplicationsTelecommunicationsIndustrial-Control Local Area Networks Transceivers for EMI-Sensitive Applications Integrated Services Digital Networks Packet SwitchingFeatureso ESD Protection for RS-485 I/O Pins±15kV—Human Body Model±8kV—IEC 1000-4-2, Contact Discharge ±15kV—IEC 1000-4-2, Air-Gap Discharge o Operate from a Single +3.3V Supply—No Charge Pump Required o Interoperable with +5V Logic o Guaranteed 12Mbps Data Rate (MAX3485E/MAX3490E/MAX3491E)o Slew-Rate Limited for Errorless Data Transmission (MAX3483E/MAX3488E) o 2nA Low-Current Shutdown Mode(MAX3483E/MAX3485E/MAX3486E/MAX3491E)o -7V to +12V Common-Mode Input Voltage Range o Full-Duplex and Half-Duplex Versions Available o Industry-Standard 75176 Pinout (MAX3483E/MAX3485E/MAX3486E)o Current-Limiting and Thermal Shutdown for Driver Overload ProtectionMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E3.3V-Powered, ±15kV ESD-Protected, 12Mbps and Slew-Rate-Limited T rue RS-485/RS-422 T ransceivers________________________________________________________________Maxim Integrated Products119-1474; Rev 0; 4/99Selector GuideOrdering InformationOrdering Information continued at end of data sheet.For free samples & the latest literature: , or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.M A X 3483E /M A X 3485E /M A X 3486E /M A X 3488E /M A X 3490E /M A X 3491E3.3V-Powered, ±15kV ESD-Protected, 12Mbps and Slew-Rate-Limited T rue RS-485/RS-422 T ransceiversABSOLUTE MAXIMUM RATINGSDC ELECTRICAL CHARACTERISTICS(V = +3.3V ±0.3V, T = T to T , unless otherwise noted.

Receiving___________Applications InformationThe MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E are low-power transceivers for RS-485 and RS-422 communications. The MAX3483E and MAX3488E can transmit and receive at data rates up to 250kbps, the MAX3486E at up to 2.5Mbps, and the MAX3485E/MAX3490E/MAX3491E at up to 12Mbps. The MAX3488E/MAX3490E/MAX3491E are full-duplex trans-ceivers, while the MAX3483E/MAX3485E/MAX3486E are half-duplex. Driver Enable (DE) and Receiver Enable (RE ) pins are included on the MAX3483E/MAX3485E/MAX3486E/MAX3491E. When disabled, the driver and receiver outputs are high impedance.Reduced EMI and Reflections (MAX3483E/MAX3486E/MAX3488E)The MAX3483E/MAX3488E are slew-rate limited, mini-mizing EMI and reducing reflections caused by improp-erly terminated cables. Figure 13 shows the driver output waveform of a MAX3485E/MAX3490E/MAX3491E transmitting a 125kHz signal, as well as the Fourier analysis of that waveform. High-frequency harmonics with large amplitudes are evident. Figure 14 shows the same information, but for the slew-rate-limited MAX3483E/MAX3488E transmitting the same signal. The high-frequency harmonics have much lower amplitudes,and the potential for EMI is significantly reduced.Low-Power Shutdown Mode(MAX3483E/MAX3485E/MAX3486E/MAX3491E)A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled (high impedance). In shutdown, the devices typically draw only 2nA of supply current.For these devices, the t PSH and t PSL enable times assume the part was in the low-power shutdown mode;the t PZH and t PZL enable times assume the receiver or driver was disabled, but the part was not shut down.MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E3.3V-Powered, ±15kV ESD-Protected, 12Mbps and Slew-Rate-Limited T rue RS-485/RS-422 T ransceivers______________________________________________________________________________________11INPUTS OUTPUT A, B RO ≥+0.2V 1≤-0.2V 0Inputs Open1INPUT OUTPUTS DI Z Y 101015MHz 500kHz/div 05MHz500kHz/div Figure 13.

MAX3485E/MAX3490E/MAX3491E System Differential Voltage at 125kHz Driving 4000 Feet of CableDriver-Output Protection Excessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short circuits over the whole common-mode voltage range (see Typical Operating Characteristics). In addition, a thermal shut-down circuit forces the driver outputs into a high-imped-ance state if the die temperature rises excessively.Propagation Delay Figures 15–18 show the typical propagation delays. Skew time is simply the difference between the low-to-high and high-to-low propagation delay. Small driver/receiver skew times help maintain a symmetrical mark-space ratio (50% duty cycle).The receiver skew time, |t PRLH- t PRHL|, is under 10ns (20ns for the MAX3483E/MAX3488E). The driver skew times are 8ns for the MAX3485E/MAX3490E/MAX3491E, 12ns for the MAX3486E, and typically under 50ns for the MAX3483E/MAX3488E.Line Length vs. Data Rate The RS-485/RS-422 standard covers line lengths up to 4000 feet. For line lengths greater than 4000 feet, see Figure 21 for an example of a line repeater.Figures 19 and 20 show the system differential voltage for parts driving 4000 feet of 26AWG twisted-pair wire at 125kHz into 120Ωloads.For faster data rate transmission, please consult the fac-tory.±15kV ESD Protection As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The driver outputs and receiver inputs of the MAX3483E family of devices have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, shutdown, and powered down. After an ESD event, Maxim’s E versions keep working without latchup or damage.ESD protection can be tested in various ways; the transmitter outputs and receiver inputs of this product family are characterized for protection to the following limits:1)±15kV using the Human Body Model2)±8kV using the Contact-Discharge method specifiedin IEC 1000-4-23)±15kV using IEC 1000-4-2’s Air-Gap method.ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body Model Figure 22a shows the Human Body Model and Figure 22b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the test device through a 1.5kΩresistor.IEC 1000-4-2 The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX3483E family of devices helps you design equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model. Figure 23a shows the IEC 1000-4-2 model, and Figure 23b shows the current waveform for the ±8kV IEC 1000-4-2, Level 4 ESD contact-discharge test.Figure 21.

The contact-discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused when I/O pins are contacted by handling equipment during test and assembly. Of course, all pins require this protection, not just RS-485 inputs and outputs.Typical ApplicationsThe MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E transceivers are designed for bidirectional data communications on multipoint bus transmission lines. Figures 24 and 25 show typical net-work applications circuits. These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 21.To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possible. The slew-rate-limited MAX3483E/MAX3488E and the partially slew-rate-limited MAX3486E are more tolerant of imperfect termination.3.3V-Powered, ±15kV ESD-Protected, 12Mbps and Slew-Rate-Limited T rue RS-485/RS-422 T ransceivers14______________________________________________________________________________________Figure 22a.

General DescriptionThe MAX4539/MAX4540 low-voltage, CMOS 8-channel (MAX4539) and dual 4-channel (MAX4540) multiplexers are ideal for precision ADC calibration and system self-monitoring applications. These calibration multiplexers (cal-muxes) have precision resistor-dividers to generate accurate voltage ratios from an input reference voltage.The reference ratios include 15/4096 and 4081/4096 of the external reference voltage, accurate to 15 bits, and 1/2V+ and 5/8(V+ - V-), accurate to 8 bits. The external reference voltage as well as ground can also be switched to the output. The MAX4539/MAX4540 have enable inputs and address latching. All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using a ±5V or a single +5V supply. Protection diodes at all inputs provide an ESD rating >2kV.The MAX4539/MAX4540 operate from a single +2.7V to +12V supply, or from dual supplies of ±2.7V to ±6V.On-resistance (100Ωmax) is matched between switch-es to 6Ωmax. Each switch can handle Rail-to-Rail ®analog signals. The off leakage current is 0.1nA at T A = +25°C and 2nA at T A = +85°C.The MAX4539/MAX4540 are available in small 20-pin DIP, SO, and SSOP packages.ApplicationsBattery-Operated Equipment AvionicsData-Acquisition Systems Audio-Signal Routing Test EquipmentNetworkingFeatureso On-Chip Gain and Offset Divider Networks Provide 15-Bit Accurate Output Ratios o On-Chip V+ to GND and V+ to V- Divider Networks Provide 8-Bit Accurate Output Ratios o R ON : 100Ωmaxo R ON Matching Between Channels: 6Ωmax o Charge Injection: 5pC max o Low 0.1nA Off Leakage Current o Small 20-Pin SSOP/SO/DIP PackagesMAX4539/MAX4540Low-Voltage, Single 8-to-1 and Dual 4-to-1 Cal-Multiplexers________________________________________________________________Maxim Integrated Products119-4780; Rev 1; 6/99Pin Configurations/_______________Functional DiagramsOrdering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.For free samples & the latest literature: , or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.M A X 4539/M A X 4540Low-Voltage, Single 8-to-1 and Dual 4-to-1 Cal-Multiplexers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual Supplies(V+ = +5V ±10%, V- = -5V ±10%, V IH = 2.4V, V IL = 0.8V, T A = T MIN to T MAX , unless otherwise noted.

Internal resistor-dividers gener-ate accurate voltage ratios from an external voltage reference, allowing zero- and full-scale calibration of ADC systems as well as facilitation of system self-moni-toring. To access the resistor-dividers, assert the CAL pin. When CAL and ENABLE are asserted, the three address pins select one of the various resistor-divider or external reference outputs. The MAX4539/MAX4540also contain a LATCH input that allows the state of the CAL and address signals to be captured.Calibration FunctionsThe Gain Divider, Offset Divider, REFHI and REFLO modes allow calibration of offset and gain errors in ADC systems. The Gain Divider mode outputs a volt-age ratio that is 4081/4096 of V REFHI - V REFLO , accu-rate to 0.1/4096, or better than 15 bits. The Offset Divider mode outputs a voltage ratio that is 15/4096 of V REFHI - V REFLO , also accurate to 0.1/4096. The REFHI mode allows the voltage on the REFHI pin to be switched to the output. The REFLO mode allows the voltage on the REFLO pin to be switched to the output.Self-Monitoring FunctionsThe self-monitoring functions are intended to allow an ADC to measure its own supply voltage. The MAX4539has an internal divide-by-two resistor string between V+and GND that is accurate to 8 bits (16/4096). It also has a 5/8 resistor string between V+ and V- that is also accurate to 8 bits. This divider string allows measure-ment of the negative supply with a unipolar ADC. GND can also be switched to the output, eliminating the need for an additional multiplexer channel.Applications InformationThe MAX4539/MAX4540’s construction is typical of most CMOS analog switches. There are three supply pins:V+, V-, and GND. The positive and negative power sup-plies provide drive to the internal CMOS switches and set the limits of the analog voltage on any switch.Reverse-biased ESD protection diodes are internally connected between each analog signal pin and both V+and V-. If the voltage on any pin exceeds V+ or V-, one of these diodes will conduct. During normal operation,these reverse-biased ESD diodes leak, forming the only current drawn from V-.Virtually all the analog-leakage current is through the ESD diodes. Although the ESD diodes on a given sig-nal pin are identical, and therefore fairly well bal-anced, they are reverse-biased differently. Each isbiased by either V+ or V- and the analog signal. This means their leakage varies as the signal varies. The difference in the two-diode leakage from the signal path to the V+ and V- pins constitutes the analog-signal path leakage current. All analog-leakage cur-rent flows to the supply terminals, not to the other switch terminal, which explains how both sides of a given switch can show leakage currents of either the same or opposite polarity.There is no connection between the analog-signal paths and GND. The analog-signal paths consist of an N-channel and P-channel MOSFET with their sources and drains paralleled and their gates driven out of phase with V+ and V- by the logic-level translators.V+ and GND power the internal logic and logic-level translators and set the input-logic thresholds. The logic-level translators convert the logic levels to switched V+and V- signals to drive the gates of the analog switches.This drive signal is the only connection between the logic supplies and the analog supplies. All pins have ESD protection to V+ and to V-.Increasing V- has no effect on the logic-level thresh-olds, but it does increase the drive to the P-channel switches, which reduces their on-resistance. V- also sets the negative limit of the analog-signal voltage.The logic-level thresholds are CMOS- and TTL- com-patible when V+ is +5V. As V+ is raised, the threshold increases slightly; when V+ reaches +12V, the level threshold is about 3.2V. Although that is above the TTL output high-level minimum of 2.4V, it is still compatible with CMOS outputs.Bipolar-Supply OperationThe MAX4539/MAX4540 operate with bipolar supplies between ±2.7V and ±6V. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 13V.Note: Do not connect the MAX4539/MAX4540 V+ pin to +3V AND connect the logic-level input pins to TTL logic-level signals. TTL logic-level outputs can exceed the absolute maximum ratings, which will cause damage to the part and/or external circuits. Caution: The absolute maximum V+ to V- differential voltage is 13V. Typical “±6-Volt” or “12-Volt” sup-plies with ±10% tolerances can be as high as 13.2V.This voltage can damage the MAX4539/MAX4540.Even ±5% tolerance supplies may have overshoot or noise spikes that exceed 13V.MAX4539/MAX4540Low-Voltage, Single 8-to-1 and Dual 4-to-1 Cal-Multiplexers______________________________________________________________________________________13Single-Supply OperationThe MAX4539/MAX4540 operate from a single supply between +2.7V and +12V when V- is connected to GND. All of the bipolar precautions must be observed.However, these parts are optimized for ±5V operation,and most AC and DC characteristics are degraded sig-nificantly when departing from ±5V. As the overall sup-ply voltage (V+ to V-) is lowered, switching speed,on-resistance, off isolation, and distortion will degrade.(see the Typical Operating Characteristics section).Single-supply operation also limits signal levels and interferes with ground referenced signals. When V- = 0,AC signals are limited to -0.3V. Voltages below -0.3V can be clipped by the internal ESD-protection diodes, and the parts can be damaged if excessive current flows.Power UpDuring power up, on-chip latches will strobe whatever addresses are present if EN goes high before LATCH reaches a logic high. When this condition occurs, one ofthe internal dividers connected between the supplies may inadvertently turn on, causing higher supply current (~200µA supply current) when the enable input is tog-gled. Avoid this condition by ensuring that EN pin stays low until the remaining logic inputs are valid. To accom-plish this, connect a resistor from EN to ground or apply a low voltage to EN before the other logic inputs go high.Power OffWhen power to the MAX4539/MAX4540 is off (i.e., V+ =V- = 0), the Absolute Maximum Ratings still apply. This means that neither logic-level inputs on NO_ nor sig-nals on COM_ can exceed ±0.3V. Voltages beyond ±0.3V cause the internal ESD-protection diodes to con-duct, and the parts can be damaged if excessive cur-rent flows.Chip InformationTRANSISTOR COUNT: 561Test Circuits/Timing DiagramsFigure 1.
