MEMORY存储芯片MAX3442EESA+T中文规格书

General DescriptionThe MAX3440E–MAX3444E fault-protected RS-485 and J1708 transceivers feature ±60V protection from signal faults on communication bus lines. Each device contains one differential line driver with three-state output and one differential line receiver with three-state input. The 1/4-unit-load receiver input impedance allows up to 128 transceiv-ers on a single bus. The devices operate from a 5V supply at data rates of up to 10Mbps. True fail-safe inputs guar-antee a logic-high receiver output when the receiver inputs are open, shorted, or connected to an idle data line.Hot-swap circuitry eliminates false transitions on the data bus during circuit initialization or connection to a live backplane. Short-circuit current-limiting and thermal shut-down circuitry protect the driver against excessive power dissipation, and on-chip ±15kV ESD protection eliminates costly external protection devices.The MAX3440E–MAX3444E are available in 8-pin SO and PDIP packages and are specified over industrial and automotive temperature ranges.Applications ●RS-422/RS-485 Communications ●Industrial Networks ●Telecommunications Systems ●HVAC Controls Features ●±15kV ESD Protection ●±60V Fault Protection ●Guaranteed 10Mbps Data Rate (MAX3441E/MAX3443E)●Hot Swappable for Telecom Applications ●True Fail-Safe Receiver Inputs ●Enhanced Slew-Rate-Limiting Facilitates Error-Free Data Transmission (MAX3440E/MAX3442E/MAX3444E)●Allow Up to 128 Transceivers on the Bus ●-7V to +12V Common-Mode Input Range ●Automotive Temperature Range (-40°C to +125°C)●Industry-Standard Pinout +Denotes a lead(Pb)-free/RoHS-compliant package.Ordering Information continued at end of data sheet.PARTTEMP RANGE PIN-PACKAGE MAX3440E ESA+-40°C to +85°C 8 SO MAX3440EEPA+-40°C to +85°C 8 PDIP MAX3440EASA+-40°C to +125°C 8 SO MAX3440EAPA+-40°C to +125°C 8 PDIPOrdering InformationMAX3440E–MAX3444E ±15kV ESD-Protected, ±60V Fault-Protected, 10Mbps, Fail-Safe RS-485/J1708 TransceiversMAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 TransceiversOD OCFigure 3.

________________General DescriptionThe MAX3224E/MAX3225E/MAX3226E/MAX3227E/MAX3244E/MAX3245E are 3V-powered EIA/TIA-232and V.28/V.24 communications interfaces with automat-ic shutdown/wakeup features, high data-rate capabili-ties, and 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.All devices achieve a 1µA supply current using Maxim’s revolutionary AutoShutdown Plus™ feature. These devices automatically enter a low-power shutdown mode when the RS-232 cable is disconnected or the transmitters of the connected peripherals are inactive,and the UART driving the transmitter inputs is inactive for more than 30 seconds. They turn on again when they sense a valid transition at any transmitter or receiv-er input. AutoShutdown Plus saves power without changes to the existing BIOS or operating system.The MAX3225E/MAX3227E/MAX3245E also feature MegaBaud™ operation, guaranteeing 1Mbps for high-speed applications such as communicating with ISDN modems. The MAX3224E/MAX3226E/MAX3244E guar-antee 250kbps operation. The transceivers have a pro-prietary low-dropout transmitter output stage enabling true RS-232 performance from a +3.0V to +5.5V supply with a dual charge pump. The charge pump requires only four small 0.1µF capacitors for operation from a 3.3V supply. The MAX3224E–MAX3227E feature a logic-level output (READY) that asserts when the charge pump is regulating and the device is ready to begin transmitting.All devices are available in a space-saving TQFN,SSOP, and TSSOP (MAX3224E/MAX3225E/MAX3244E/MAX3245E) packages.________________________ApplicationsNotebook, Subnotebook, and Palmtop Computers Cellular PhonesBattery-Powered Equipment Hand-Held Equipment Peripherals Printers__Next Generation Device Features♦For Space-Constrained Applications:MAX3228E/MAX3229E: ±15kV ESD-Protected,+2.5V to +5.5V, RS-232 Transceivers in UCSP MAX3222E/MAX3232E/MAX3241E †/MAX3246E:±15kV ESD-Protected, Down to 10nA, +3.0V to +5.5V, Up to 1Mbps, True RS-232 Transceivers (MAX3246E Available 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 PinsMAX3224E–MAX3227E/MAX3244E/MAX3245E †±15kV ESD-Protected, 1µA, 1Mbps, 3.0V to 5.5V ,RS-232 Transceivers with AutoShutdown Plus________________________________________________________________Maxim Integrated Products119-1339; Rev 9; 2/07Ordering Information continued at end of data sheet.*EP = Exposed paddle.†Covered by U.S. Patent numbers 4,636,930; 4,679,134; 4,777,577;4,797,899; 4,809,152; 4,897,774; 4,999,761; 5,649,210; and other patents pending.AutoShutdown Plus, MegaBaud, and UCSP are trademarks of Maxim Integrated Products, Inc.Ordering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 3224E –M A X 3227E /M A X 3244E /M A X 3245E †±15kV ESD-Protected, 1µA, 1Mbps, 3.0V to 5.5V ,RS-232 Transceivers with AutoShutdown PlusABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V CC = +3V to +5.5V, C1–C4 = 0.1µF, tested at 3.3V ±10%; C 1= 0.047µF, C2–C4 = 0.33µF, tested at 5.0V ±10%; T A = T MIN to T MAX ,unless otherwise noted.

The charge pump operates in discontinuous mode: if the output voltages are less than 5.5V, the charge pump ischarge-pump is disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies.The READY output (MAX3224E–MAX3227E) is low when the charge pumps are disabled in shutdown mode. The READY signal asserts high when V- goes below -4V.MAX3224E–MAX3227E/MAX3244E/MAX3245E †±15kV ESD-Protected, 1µA, 1Mbps 3.0V to 5.5V ,RS-232 Transceivers with AutoShutdown Plus_______________________________________________________________________________________9RS-232 TransmittersThe transmitters are inverting level translators that convert CMOS-logic levels to 5.0V EIA/TIA-232 levels.The MAX3224E/MAX3226E/MAX3244E guarantee a 250kbps data rate (1Mbps, for the MAX3225E/MAX3227E/MAX3245E) with worst-case loads of 3k Ωin parallel with 1000pF, providing compatibility with PC-to-PC com-munication software (such as LapLink™). Transmitters can be paralleled to drive multiple receivers. Figure 1shows a complete system connection.When FORCEOFF is driven to ground or when the Auto-Shutdown Plus circuitry senses that all receiver and transmitter inputs are inactive for more than 30s, the transmitters are disabled and the outputs go into a high-impedance state. When powered off or shut down, the outputs can be driven to ±12V. The transmitter inputs do not have pullup resistors. Connect unused inputs to GND or V CC .Figure 1.

The MAX3224E–MAX3227E feature inverting outputs that always remain active (Table 1).The MAX3244E/MAX3245E have inverting three-state outputs that are high impedance when shut down (FORCEOFF = GND) (Table 1).The MAX3244E/MAX3245E feature an extra, always active, noninverting output, R2OUTB. R2OUTB output monitors receiver activity while the other receivers are high impedance, allowing ring indicator applications to be monitored without forward biasing other devices connected to the receiver outputs. This is ideal for sys-tems where V CC is set to ground in shutdown to accommodate peripherals such as UARTs (Figure 2).The MAX3224E–MAX3227E/MAX3244E/MAX3245E fea-ture an INVALID output that is enabled low when no valid RS-232 voltage levels have been detected on all receiver inputs. Because INVALID indicates the receiv-er input’s condition, it is independent of FORCEON and FORCEOFF states (Figures 3 and 4).AutoShutdown Plus ModeThe MAX3224E–MAX3227E/MAX3244E/MAX3245E achieve a 1µA supplycurrent with Maxim’s AutoShutdown Plus feature, which operates when FORCEOFF is high and a FORCEON is low. When these devices do not sense a valid signal transition on any receiver and trans-mitter input for 30s, the on-board charge pumps are shut down, reducing supply current to 1µA. This occurs if the RS-232 cable is disconnected or if the connectedTable 1.

The system turns on again when a valid transition is applied to any RS-232 receiver or transmitter input. As a result, the sys-tem saves power without changes to the existing BIOS or operating system.Figures 3a and 3b depict valid and invalid RS-232receiver voltage levels. INVALID indicates the receiver input’s condition, and is independent of FORCEON and FORCEOFF states. Figure 3 and Tables 1 and 2 sum-marize the operating modes of the MAX3224E–MAX3227E/MAX3244E/MAX3245E. FORCEON and FORCEOFF override AutoShutdown Plus circuitry.When neither control is asserted, the IC selects between these states automatically based on the last receiver or transmitter input edge received.When shut down, the device’s charge pumps turn off,V+ is pulled to V CC , V- is pulled to ground, the transmit-ter outputs are high impedance, and READY (MAX3224E–MAX3227E) is driven low. The time required to exit shutdown is typically 100µs (Figure 8).By connecting FORCEON to INVALID , the MAX3224E–MAX3227E/MAX3244E/MAX3245E shut down when no valid receiver level and no receiver or transmitter edge is detected for 30s, and wake up when a valid receiver level or receiver or transmitter edge is detected.Figure 3a.

Figure 5 shows a circuit that forces the transmitters on for 100ms, allowing enough time for the other system to realize that the MAX3244E/MAX3245E is awake. If the other system outputs valid RS-232 signal transitions within that time, the RS-232ports on both systems remain enabled.Software-Controlled ShutdownIf direct software control is desired, use INVALID to indicate DTR or ring indicator signal. Tie FORCEOFF and FORCEON together to bypass the AutoShutdown Plus so the line acts like a SHDN input.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electrostaticdischarges encountered during handling and assembly.The driver outputs and receiver inputs of the MAX3224E–MAX3227E/MAX3244E/MAX3245E have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protectFigure 4b. AutoShutdown Plus, INVALID,and READY Timing DiagramFigure 5. AutoShutdown Plus Initial Turn-On to Wake Up a Mouse or Another SystemMAX3224E–MAX3227E/MAX3244E/MAX3245E †±15kV ESD-Protected, 1µA, 1Mbps 3.0V to 5.5V ,RS-232 Transceivers with AutoShutdown Plusthese 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, whereas competing RS-232 products can latch and must be powered down to remove latchup.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 specified in IEC1000-4-23)±15kV using IEC1000-4-2’s Air-Gap Method.ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 6a shows the Human Body Model and Figure 6b 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 1.5k Ωresistor.Figure 6b.

IEC1000-4-2 ESD Test ModelM A X 3224E –M A X 3227E /M A X 3244E /M A X 3245E †±15kV ESD-Protected, 1µA, 1Mbps 3.0V to 5.5V ,RS-232 Transceivers with AutoShutdown Plus IEC1000-4-2The IEC1000-4-2 standard covers ESD testing and per-formance of finished equipment; it does not specifically refer to integrated circuits. The MAX3224E–MAX3227E,MAX3244E/MAX3245E help you design equipment that meets Level 4 (the highest level) of IEC1000-4-2, with-out the need for additional ESD-protection components.The major difference between tests done using the H uman Body Model and IEC1000-4-2 is higher peak current in IEC1000-4-2, because series resistance is lower in the IEC1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC1000-4-2 is generally lower than that measured using the H uman Body Model. Figure 7a shows the IEC1000-4-2 model and Figure 7b shows the current waveform for the 8kV,IEC1000-4-2, Level 4, ESD Contact-Discharge Method.The Air-Gap Method involves approaching the device with a charged probe. 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 by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protec-tion during manufacturing, not just RS-232 inputs and outputs. Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.__________Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; polarized or nonpolarized capacitorscan be used. The charge pump requires 0.1µF capaci-tors for 3.3V operation. For other supply voltages, see Table 3 for required capacitor values. Do not use val-ues smaller than those listed in Table 3. Increasing the capacitor values (e.g., by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1without also increasing the values of C2, C3, C4,and C BYPASS , to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degrade excessively with temperature. If in doubt, use capaci-tors with a larger nominal value. The capacitor’s equiv-alent series resistance (ESR), which usually rises at low temperatures, influences the amount of ripple on V+and V-.Power-Supply DecouplingIn most circumstances, a 0.1µF V CC bypass capacitor is adequate. In applications that are sensitive to power-supply noise, use a capacitor of the same value as charge-pump capacitor C1. Connect bypass capaci-tors as close to the IC as possible.Transmitter Outputs when Exiting ShutdownFigure 8 shows two transmitter outputs when exiting shutdown mode. As they become active, the two trans-mitter outputs are shown going to opposite RS-232 lev-els (one transmitter input is high, the other is low). Each5μs/divV CC = 3.3V C1–C4 = 0.1μFFigure 8. Transmitter Outputs when Exiting Shutdown or Powering Uptransmitter is loaded with 3k Ωin parallel with 1000pF.The transmitter outputs display no ringing or undesir-able transients as they come out of shutdown. Note that the transmitters are enabled only when the magnitude of V- exceeds approximately -3V.High Data RatesThe MAX3224E/MAX3226E/MAX3244E maintain the RS-232 ±5.0V minimum transmitter output voltage even at high data rates. Figure 9 shows a transmitter loop-back test circuit. Figure 10 shows a loopback test result at 120kbps, and Figure 11 shows the same test at 250kbps. For Figure 10, all transmitters were driven simultaneously at 120kbps into RS-232 loads in parallel with 1000pF. For Figure 11, a single transmitter was dri-ven at 250kbps, and all transmitters were loaded with an RS-232 receiver in parallel with 250pF.The MAX3225E/MAX3227E/MAX3245E maintain the RS-232 ±5.0V minimum transmitter output voltage at data rates up to 1Mbps (MegaBaud). Figure 12 shows a loopback test result with a single transmitter driven at 1Mbps and all transmitters loaded with an RS-232receiver in parallel with 250pF.MAX3224E–MAX3227E/MAX3244E/MAX3245E †±15kV ESD-Protected, 1µA, 1Mbps 3.0V to 5.5V ,RS-232 Transceivers with AutoShutdown PlusFigure 9.

Integrated | 10Shutdown and Enable Control (MAX205E/MAX206E/MAX211E/MAX213E/MAX241E)In shutdown mode, the charge pumps are turned off,V+ is pulled down to V CC , V- is pulled to ground, and the transmitter outputs are disabled. This reduces sup-ply current typically to 1µA (15µA for the MAX213E).The time required to exit shutdown is under 1ms, asshown in Figure 5.Receivers All MAX213E receivers, except R4 and R5, are put into a high-impedance state in shutdown mode (see Tables 1a and 1b). The MAX213E’s R4 and R5 receivers still function in shutdown mode. These two awake-in-shut-down receivers can monitor external activity while main-taining minimal power consumption.The enable control is used to put the receiver outputs into a high-impedance state, to allow wire-OR connection of two EIA/TIA-232E ports (or ports of different types) at the UART. It has no effect on the RS-232 drivers or the charge pumps.Note: The enable c ontrol pin is ac tive low for the MAX211E/MAX241E (EN ), but is ac tive high for theMAX213E (EN). The shutdown control pin is active highFigure 4. Charge-Pump DiagramWhen in low-power shutdown mode, the MAX205E/MAX206E/MAX211E/MAX213E/MAX241E driver outputsare turned off and draw only leakage currents—even ifthey are back-driven with voltages between 0V and12V. Below -0.5V in shutdown, the transmitter output isdiode-clamped to ground with a 1k Ω series imped-ance.RS-232 ReceiversThe receivers convert the RS-232 signals to CMOS-logicoutput levels. The guaranteed 0.8V and 2.4V receiverinput thresholds are significantly tighter than the ±3Vthresholds required by the EIA/TIA-232E specification.This allows the receiver inputs to respond to TTL/CMOS-logic levels, as well as RS-232 levels.The guaranteed 0.8V input low threshold ensures thatreceivers shorted to ground have a logic 1 output. The5k Ω input resistance to ground ensures that a receiverwith its input left open will also have a logic 1 output.Receiver inputs have approximately 0.5V hysteresis.This provides clean output transitions, even with slowrise/fall-time signals with moderate amounts of noiseand ringing.In shutdown, the MAX213E’s R4 and R5 receivers haveno hysteresis.找MEMORY 、二三极管上美光存储Integrated | 13MAX202E–MAX213E,MAX232E/MAX241E ±15kV ESD-Protected, 5V RS-232 Transceivers outputs. Therefore,after PC board assembly,theMachine Model is less relevant to I/O ports.Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical forproper operation. The MAX202E, MAX206–MAX208E,MAX211E, and MAX213E require 0.1µF capacitors,and the MAX232E and MAX241E require 1µF capaci-tors, although in all cases capacitors up to 10µF canbe used without harm. Ceramic, aluminum-electrolytic,or tantalum capacitors are suggested for the 1µFcapacitors, and ceramic dielectrics are suggested forthe 0.1µF capacitors. When using the minimum recom-mended capacitor values, make sure the capacitancevalue does not degrade excessively as the operatingtemperature varies. If in doubt, use capacitors with alarger (e.g., 2x) nominal value. The capacitors’ effec-tive series resistance (ESR), which usually rises at lowtemperatures, influences the amount of ripple on V+and V-.Use larger capacitors (up to 10µF) to reduce the outputimpedance at V+ and V-. This can be useful when“stealing” power from V+ or from V-. The MAX203E andMAX205E have internal charge-pump capacitors.Bypass V CC to ground with at least 0.1µF. In applica-tions sensitive to power-supply noise generated by the charge pumps, decouple V CC to ground with a capaci-tor the same size as (or larger than) the charge-pump capacitors (C1–C4).V+ and V- as Power Supplies A small amount of power can be drawn from V+ and V-,although this will reduce both driver output swing and noise margins. Increasing the value of the charge-pump capacitors (up to 10µF ) helps maintain performance when power is drawn from V+ or V-.Driving Multiple Receivers Each transmitter is designed to drive a single receiver.Transmitters can be paralleled to drive multiple receivers.Driver Outputs when Exiting Shutdown The driver outputs display no ringing or undesirable transients as they come out of shutdown.High Data Rates These transceivers maintain the RS-232 ±5.0V mini-mum driver output voltages at data rates of over 120kbps. F or data rates above 120kbps, refer to the Transmitter Output Voltage vs. Load Capacitance graphs in the Typical Operating Characteristics .Communication at these high rates is easier if the capacitive loads on the transmitters are small; i.e.,short cables are best.Table 2.

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 DelayFigures 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, |tPRLH - 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 RateThe 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 120Ω loads.For faster data rate transmission, please consult the factory.±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 trans-mitter outputs and receiver inputs of this product family are characterized for protection to the following limits:1)±15kV using the Human Body Model 2)±8kV using the Contact-Discharge method specified in 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 interest, which is then discharged into the test device through a 1.5kΩ resistor.IEC 1000-4-2The 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 cur-rent in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD withstand 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 4ESD contact-discharge test. test.Figure 21.

General DescriptionThe MAX4561/MAX4568/MAX4569 are low-voltage,ESD-protected analog switches. The normally open (NO) and normally closed (NC) inputs are protected against ±15kV electrostatic discharge (ESD) without latchup or damage, and the COM input is protected against 2.5kV ESD.These switches operate from a single +1.8V to +12V supply. The 70Ωat 5V (120Ωat 3V) on-resistance is matched between channels to 2Ωmax, and is flat (4Ωmax) over the specified signal range. The switches can handle Rail-to-Rail ® analog signals. Off-leakage current is only 0.5nA at +25°C and 5nA at +85°C. The digital input has +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply. The MAX4561 is a single-pole/double-throw (SPDT) switch. The MAX4568 NO and MAX4569 NC are single-pole/single-throw (SPST) switches.The MAX4561 is available in a 6-pin SOT23 package,and the MAX4568/MAX4569 are available in 5-pin SOT23 packages.________________________ApplicationsHigh-ESD Environments Battery-Powered Systems Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Sample-and-Hold Circuits Communications CircuitsFeatureso ESD-Protected NO, NC±15kV—Human Body Model±15kV—IEC 1000-4-2, Air-Gap Discharge ±8kV—IEC 1000-4-2, Contact Discharge o Guaranteed On-Resistance70Ω+5V Supply120Ωwith Single +3V Supplyo On-Resistance Match Between Channels (2Ωmax)o Low On-Resistance Flatness: 4Ωmax o Guaranteed Low Leakage Currents0.5nA Off-Leakage (at T A = +25°C)0.5nA On-Leakage (at T A = +25°C)o Guaranteed Break-Before-Make at 5ns(MAX4561 only)o Rail-to-Rail Signal Handling Capabilityo TTL/CMOS-Logic Compatible with +5V Supplies o Industry Standard Pin-OutsMAX4561 Pin Compatible with MAX4544MAX4568/MAX4569 Pin Compatible with MAX4514/MAX4515MAX4561/MAX4568/MAX4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches________________________________________________________________Maxim Integrated Products 1Pin Configurations/Functional Diagrams/Truth Tables19-1714; Rev 0; 4/00For free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.Ordering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.查询MAX4561EUT-T供应商M A X 4561/M A X 4568/M A X 4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —Single +5V Supply(V+ = +4.5V to +5.5V, V IH = +2.4V, V IL = +0.8V, T A = T MIN to T MAX , unless otherwise specified.

To accomplish this, bidirectional SCRs are included on-chip between these terminals. When the voltages at these terminals go Beyond-the-Rails ™,the corresponding SCR turns on in a few nanoseconds and bypasses the surge safely to ground. This method is superior to using diode clamps to the supplies because unless the supplies are very carefully decou-pled through low-ESR capacitors, the ESD current through the diode clamp could cause a significant spike in the supplies. This may damage or compromise the reliability of any other chip powered by those same supplies.There are diodes from NC/NO to the supplies in addi-tion to the SCRs. A resistance in series with each of these diodes limits the current into the supplies during an ESD strike. The diodes protect these terminals from overvoltages that are not a result of ESD strikes. These diodes also protect the device from improper power-supply sequencing.Once the SCR turns on because of an ESD strike, it remains on until the current through it falls below its “holding current.” The holding current is typically 110mA in the positive direction (current flowing into the NC/NO terminal) at room temperature (see SCR Holding Current vs.Temperature in the Typical Operating Characteristics ). Design the system so that any sources connected to NC/NO are current-limited to a value below the holding current to ensure the SCR turns off when the ESD event is finished and normal operation resumes. Also, remember that the holding current varies significantly with temperature. The worst case is at +85°C when the holding currents drop to 70mA. Since this is a typical number to guarantee turn-off of the SCRs under all conditions, the sources con-nected to these terminals should be current-limited to no more than half this value. When the SCR is latched,the voltage across it is approximately 3V. The supply voltages do not affect the holding current appreciably.The sources connected to the COM side of the switches need not be current limited since the switches turn off internally when the corresponding SCR(s) latch.Even though most of the ESD current flows to GND through the SCRs, a small portion of it goes into V+.Therefore, it is a good idea to bypass the V+ with 0.1µF capacitors directly to the ground plane.ESD protection can be tested in various ways. Inputs are characterized for protection to the following:•±15kV using the Human Body Model•±8kV using the Contact Discharge method speci-fied in IEC 1000-4-2 (formerly IEC 801-2)•±15kV using the Air-Gap Discharge method speci-fied in IEC 1000-4-2 (formerly IEC 801-2)ESD Test ConditionsContact Maxim Integrated Products for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 6 shows the Human Body Model, and Figure 7shows the waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which can be dis-charged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX4561 enables the design of equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without additional ESD protec-tion components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak cur-rent in IEC 1000-4-2. Because series resistance is lower in the IEC 1000-4-2 ESD test model (Figure 8), the ESD withstand voltage measured to this standard is generally lower than that measured using the Human Body Model.Figure 9 shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Chip InformationPROCESS: CMOSBeyond-the-Rails is a trademark of Maxim Integrated Products.TRANSISTOR COUNT: 69(MAX4561)39(MAX4568/MAX4569)M A X 4561/M A X 4568/M A X 4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches 8_______________________________________________________________________________________Figure 1.

These high-performance, dual/triple-output devices include on-board power-up sequencing, power-good signaling with delay, digital soft-start, secondary winding control, low-dropout circuitry, internal frequency-compensation net-works, and automatic bootstrapping. Up to 96% efficiency is achieved through synchronous rectification and Maxim’s proprietary Idle Mode™ control scheme. Efficiency is greater than 80% over a 1000:1load-current range, which extends battery life in system-suspend or standby mode. Excellent dynamic response corrects output load transients caused by the latest dynamic-clock CPUs within five 300kHz clock cycles.Strong 1A on-board gate drivers ensure fast external N-channel MOSFET switching. These devices feature a logic-controlled and synchroniz-able, fixed-frequency, pulse-width-modulation (PWM)operating mode. This reduces noise and RF interference in sensitive mobile communications and pen-entry appli-cations. Asserting the SKIP pin enables fixed-frequency mode, for lowest noise under all load conditions. The MAX1630–MAX1635 include two PWM regulators,adjustable from 2.5V to 5.5V with fixed 5.0V and 3.3V modes. All these devices include secondary feedbackregulation, and the MAX1630/MAX1632/MAX1633/MAX1635 each contain 12V/120mA linear regulators. The MAX1631/MAX1634 include a secondary feedback input(SECF B), plus a control pin (STEER) that selects which PWM (3.3V or 5V) receives the secondary feedback sig-nal. SECF B provides a method for adjusting the sec-ondary winding voltage regulation point with an external resistor divider, and is intended to aid in creating auxiliaryvoltages other than fixed 12V.The MAX1630/MAX1631/MAX1632 contain internal out-put overvoltage and undervoltage protection features.________________________Applications Notebook and Subnotebook Computers PDAs and Mobile CommunicatorsDesktop CPU Local DC-DC Converters____________________________Features ♦96% Efficiency♦+4.2V to +30V Input Range♦2.5V to 5.5V Dual Adjustable Outputs ♦Selectable 3.3V and 5V Fixed or Adjustable Outputs (Dual Mode™)♦12V Linear Regulator♦Adjustable Secondary Feedback(MAX1631/MAX1634)♦5V/50mA Linear Regulator Output♦Precision 2.5V Reference Output♦Programmable Power-Up Sequencing♦Power-Good (RESET) Output♦Output Overvoltage Protection(MAX1630/MAX1631/MAX1632)♦Output Undervoltage Shutdown(MAX1630/MAX1631/MAX1632)♦200kHz/300kHz Low-Noise, Fixed-Frequency Operation♦Low-Dropout, 99% Duty-Factor Operation ♦2.5mW Typical Quiescent Power (+12V input, both SMPSs on)♦4μA Typical Shutdown Current♦28-Pin SSOP PackageMAX1630–MAX1635________________________________________________________________ Integrated Products 1________________Functional Diagram _______________Ordering Information Ordering Information continued at end of data sheet.Pin Configurations and Selector Guide appear at end of datasheet.Idle Mode and Dual Mode are trademarks of Integrated Products.+Denotes lead-free package.找MEMORY 、二三极管上美光存储M A X 1630–M A X 1635Multi-Output, Low-Noise Power-Supply Controllers for Notebook Computers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS(V+ = 15V, both PWMs on, SYNC = VL, VL load = 0mA, REF load = 0mA, SKIP = 0V, T A = T MIN to T MAX , unless otherwise noted.Typical values are at T A = +25°C.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

3V Dual RS-232 Transceiver with LCD Supply and Contrast Controller
General Description
The MAX3325 integrates a two-transmitter, two-receiver RS-232 transceiver with an LCD supply plus temperature-compensated contrast control. It is intended for small 3V instruments requiring a 5V supply for either logic or an LCD display, an adjustable bias signal for contrast, LCD temperature compensation, and an RS-232 interface for serial communications. The 5V supply is a regulated charge pump followed by a low-dropout (LDO) linear regulator capable of supplying 11mA for the 5V LCD power. The MAX3325 has an internal 6-bit digital-to-analog converter (DAC) providing 64 contrast levels, plus an internal temperature sensor that compensates the LCD’s contrast for changes in ambient temperature. The LCD contrast can be designed for any voltage range from -5V to +2V. The MAX3325’s 250kbps RS-232 transceiver meets all EIA-232E specifications with input voltages from +3.0V to +3.6V. Both the RS-232 section and the LCD supply circuitry can be independently placed in shutdown, tailoring power consumption for battery-powered equipment. The MAX3325 is available in 28-pin SSOP and narrow DIP packages.
