Typical properties for CHO-SEAL 1310 and 1273 materi-al are shown on pages 33 and 32respectively.High Shielding PerformanceCHO-SEAL 1310 material provides more than 80 dB of shielding effectiv-ness from 100 MHz to 10 GHz, while CHO-SEAL 1273 material provides more than 100 dB.Low Volume ResistivityBoth materials have exceptionally low volume resistivity, which makes them well suited for grounding appli-cations in which a flexible electrical contact is needed.Low Compression GasketSpacer gaskets are typicallydesigned to function under low deflec-tion forces. Chomerics uses design tools such as Finite Element Analysis (FEA) to accurately predict compres-sion-deflection behavior of various cross section options. Refer to page16.LCP Plastic SpacerLiquid crystal polymer (LCP)spacers, including those made with Vectra A130 material, provide aCHO-SEAL ®1310 or 1273Conductive ElastomersWith EMI spacer gaskets, shielding and grounding are provided by Chomerics’CHO-SEAL 1310 and 1273 conductive elastomers, specifi-cally formulated for custom shape molded parts. They provide excellent shielding and isolation against electro-magnetic interference (EMI), or act as a low impedance ground path between PCB traces and shielding media. Physically tough, these elas-tomers minimize the risk of gasket damage, in contrast to thin-walled extrusions or unsupported molded gaskets.Silicone-based CHO-SEAL 1310and 1273 materials offer excellent resistance to compression set over a wide temperature range, resulting in years of continuous service. CHO-SEAL 1310 material is filled with silver-plated-glass particles, while 1273 utilizes silver-plated-copper filler to provide higher levels of EMI shielding effectiveness.EMI Spacer GasketsThe unique design of Chomerics’EMI spacer gaskets features a thin plastic retainer frame onto which a conductive elastomer is molded. The elastomer can be located inside or outside the retainer frame, as well as on its top and bottom surface. EMI spacer gaskets provide a newapproach to designing EMI gaskets into handheld electronics such as dig-ital cellular phones. Board-to-board spacing is custom designed to fit broad application needs. Customized cross sections and spacer shapes allow for very low closure forcerequirements and a perfect fit in any design or device.Robotic InstallationSpacer gaskets can be installed quickly by robotic application. Integral locater pins in the plastic spacer help ensure accuratepositioning in both manual and pick-and-place assembly. Benefits include faster assembly and lower labor costs.The integrated conductive elastomer/plastic spacer gasket is a low cost,easily installed system for providing EMI shielding and grounding in small electronic enclosures.Figure 1Single Piece EMI Gasket/Locator PinsCHO-SEAL 1310 or 1273 Conductive Elastomer (Inside)Plastic Spacer Around Outsideor InsideApplications for EMI Spacer GasketsThe spacer gasket concept is especially suited to digital and dual board telephone handsets or other handheld electronic devices. It provides a low impedance path between peripheral ground traces on printed circuit boards and components such as:•the conductive coating on a plastic housing•another printed circuit board •the keypad assemblyTypical applications for EMI spacer gaskets include:•Digital cellular, handyphone and personal communications services (PCS) handsets •PCMCIA cards•Global Positioning Systems (GPS)•Radio receivers•Other handheld electronics, e.g.,personal digital assistants (PDAs)•Replacements for metal EMI shield-ing “fences” on printedcircuit boards in wireless tele-communications devicesstable platform for direct, highprecision molding of conductive elas-tomers. The Vectra A130 material described in Table 1 has excellent heat deflection temperature character-istics (489°F, 254°C). For weight con-siderations, the LCP has aspecific gravity of only 1.61. This plas-tic is also 100% recyclable.Typical EMI Spacer Gasket Design ParametersThe EMI spacer gasket concept can be considered using the design parameters shown in Table 2. Some typical spacer gasket profiles are shown below.Figure 2Typical Spacer Gasket Profiles3US Headquarters TEL +(1) 781-935-4850FAX +(1) 781-933-4318 • Europe TEL +(44) 1628 404000FAX +(44) 1628 404090Asia Pacific TEL +(852) 2 428 8008FAX +(852) 2 423 8253South America TEL +(55) 11 3917 1099FAX +(55) 11 3917 0817Finite Element AnalysisChomerics, a division of the Parker Hannifin Corporation’s Seal Group, is the headquarters of Parker Seal’s Elastomer Simulation Group. This unit specializes in elastomer finite element analysis (FEA) using MARC K6 series software as a foundation for FEA capability.Benefits of FEA include:•Quickly optimizing elastomer gasket designs•Allowing accurate predictions of alternate elastomer design concepts •Eliminating extensive trial and error prototype evaluationTypical use of FEA in EMI spacer gasket designs is to evaluate the force vs. deflection requirements of alternate designs.For example, onespacer design features a continuous bead of con-ductive elastomer molded onto a plastic spacer. An alternative designemploys an “interrupted bead,” where the interrup-tions (gaps left on the plastic frame) are sized to maintain the requiredlevel of EMI shielding. Figure 4illustrates these alternative designs.Gasket DeflectionFigure 5 compares the effect of continuous and interrupted elastomer gasket designs in terms of the force required to deflect the conductive elastomer. This actual cellular handset application required a spacer gasket with interrupted bead to meet desired deflection forces.Chomerics Designand Application ServicesChomerics will custom design a spacer for your application. Advice,analysis and design assistance will be provided by Chomerics Applications and Design engineers at no additional fee.

It has the capability to drivelarge gate-charge MOSFETs and supports high PWM frequency. In sleep mode its supply current is very low.FUNCTIONAL TERMINAL DESCRIPTIONSUPPLY VOLTAGE TERMINALS (VCC AND VCC2)The VCC and VCC2 terminals are the power supply inputs to the device. V CC is used for the output high-side drivers and the charge pump. V CC2 is used for the linear regulation. They can be connected together or independent with different voltage values. The device can operate with V CC up to 55 V and V CC2 up to 28 V.The VCC and VCC2 terminals have undervoltage (UV) and overvoltage (OV) shutdown. If one of the supply voltage drops below the undervoltage threshold or rises above the overvoltage threshold, the gate outputs are switched LOW in order to switch off the external MOSFETs. When the supply returns to a level that is above the UV threshold or below the OV threshold, the device resumes normal operationaccording to the established condition of the input terminals.INPUT HIGH- AND LOW-SIDE TERMINALS (IN_HS1, IN_HS2, AND IN_LS1, IN_LS2)The IN_HSn and IN_LSn terminals are input control terminals used to control the gate outputs. These terminals are 5.0 V CMOS-compatible inputs with hysteresis. IN_HSn and IN_LSn independently control GATE_HSn and GATE_LSn, respectively.During wake-up, the logic is supplied from the G_EN terminal. There is no internal circuit to prevent the external high-side and low-side MOSFETs from conducting at the same time.SOURCE OUTPUT HIGH-SIDE TERMINALS (SRC_HS1 AND SRC_HS2)The SRC_HSn terminals are the sources of the external high-side MOSFETs. The external high-side MOSFETs are controlled using the IN_HSn inputs.GATE HIGH- AND LOW-SIDE TERMINALS (GATE_HS1, GATE_HS2, AND GATE_LS1, GATE_LS2)The GATE_HSn and GATE_LSn terminals are the gates of the external high- and low-side MOSFETs. The external high- and low-side MOSFETs are controlled using the IN_HSn and IN_LSn inputs.GLOBAL ENABLE (G_EN)The G_EN terminal is used to place the device in a sleep mode. When the G_EN terminal voltage is a logic LOW state, the device is in sleep mode. The device is enabled and fully operational when the G_EN terminal voltage is logic HIGH, typically 5.0 V.CHARGE PUMP OUT (CP_OUT)The CP_OUT terminal is used to connect an external reservoir capacitor for the charge pump.CHARGE PUMP CAPACITOR TERMINALS (C1 AND C2)The C1 and C2 terminals are used to connect an external capacitor for the charge pump.LINEAR REGULATOR OUTPUT (LR_OUT)The LR_OUT terminal is the output of the internal regulator. It is used to connect an external capacitor.GROUND TERMINALS (GND_A, GND1 AND GND2)These terminals are the ground terminals of the device. They should be connected together with a very low impedance connection.FUNCTIONAL DESCRIPTIONFUNCTIONAL TERMINAL DESCRIPTIONTable 5.

In the schematic, HSS represents the switch that is used to charge the external high-side MOSFET through the GATE_HS terminal. LSS represents the switch that is used to discharge the external high-side MOSFET through the GATE_HS terminal. A 180K Ω internal typical passivedischarge resistance and a 18 V typical protection zener are in parallel with LSS. The same schematic can be applied to the external low-side MOSFET driver simply by replacing terminal CP_OUT with terminal LR_OUT, terminal GATE_HS with terminal GATE_LS, and terminal SRC_HS with GND.Figure 5. High-Side Gate Driver Functional SchematicThe different voltages and current of the high-side gate driver are illustrated in Figure 6. The output driver sources a peak current of up to 1.0 A for 200 ns to turn on the gate. After 200 ns, 100 mA is continuously provided to maintain the gate charged. The output driver sinks a high current to turn off the gate. This current can be up to 1.0 A peak for a 100 nF load.Note G ATE_HS is loaded with a 100 nF capacitor in thechronograms. A smaller load will give lower peak and DC charge or discharge currents.Figure 6.

These scenarios are presented in Figure 7. In order to withstand high dV/dt spikes, a low resistive path between gate and source is implemented during the OFF-state.Figure 7.

If V CC2 exceeds 15.0 V, the output is limited to 14.5 V (typical).The low-drop linear regulator provides the 5.0 V for the logic section of the driver, the V gs_ls buffered at LR_OUT, and the +14.5 V for the charge pump, which generates theCP_OUT The low-drop linear regulator provides 4.0 mA average current per driver stage.In case of the full bridge, that means approximately16 mA —8.0 mA for the high side and 8.0 mA for the low side.Note: The average current required to switch a gate with a frequency of 100 kHz is:I CP = Q g * f PWM = 80 nC * 100 kHz = 8.0 mAIn a full-bridge application only one high side and one low side switches on or off at the same time.CHARGE PUMPThe charge pump generates the high-side driver supply voltage (CP_OUT), buffered at C CP_OUT. Figure 8 shows the charge pump basic circuit without load.Figure 8. Charge Pump Basic CircuitWhen the oscillator is in low state [(1) in Figure 8], C CP is charged through D2 until its voltage reaches V CC - V D2. When the oscillator is in high state (2), C CP is discharged though D1 in C CP_OUT, and final voltage of the charge pump, V CP_OUT, is V cc+ V LR_OUT - 2V D. The frequency of the 33883 oscillator is about 330 kHz.EXTERNAL CAPACITORS CHOICEExternal capacitors on the charge pump and on the linear regulator are necessary to supply high peak current absorbed during switching.Figure 9 represents a simplified circuitry of the high-side gate driver. Transistors Tosc1 and Tosc2 are the oscillator-switching MOSFETs. When Tosc1 is on, the oscillator is at low level. When Tosc2 is on, the oscillator is at high level. The capacitor C CP_OUT provides peak current to the high-sideFUNCTIONAL DEVICE OPERATIONOPERATIONAL MODESC CPC CP choice depends on power MOSFET characteristics and the working switching frequency. Figure 10 contains two diagrams that depict the influence of C CP value on V CP_OUT average voltage level. The diagrams represent two different frequencies for two power MOSFETs, MTP60N06HD and MPT36N06V.Figure 10. V CP_OUT Versus C CPThe smaller the C CP value is, the smaller the V CP_OUT value is. Moreover, for the same C CP value, when the switching frequency increases, the average V CP_OUT level decreases. For most of the applications, a typical value of 33 nF is recommended.C CP_OUTFigure 11 depicts the simplified C CP_OUT current and voltage waveforms. f PWM is the working switching frequency.CP_OUTWaveformsAs shown above, at high-side MOSFET turn-on V CP_OUTvoltage decreases. This decrease can be calculatedaccording to the C CP_OUT value as follows:Where Q g is power MOSFET gate charge.C LR_OUTC LR_OUT provides peak current needed by the low-sideMOSFET turn-on. V LR_OUT decrease is as follows:TYPICAL VALUES OF CAPACITORSIn most working cases the following typical values arerecommended for a well-performing charge pump:C CP = 33 nF, C CP_OUT = 470 nF, and C LR_OUT = 470 nFThese values give a typical 100 mV voltage ripple onV CP_OUT and V LR_OUT with Q g = 50 nC.g∆V CP_OUT =C CP_OUTQ g∆V LR_OUT =C LR_OUTQ gFUNCTIONAL DEVICE OPERATIONPROTECTION AND DIAGNOSTIC FEATURESPROTECTION AND DIAGNOSTIC FEATURESGATE PROTECTIONThe low-side driver is supplied from the built-in low-drop regulator. The high-side driver is supplied from the internal charge pump buffered at CP_OUT.The low-side gate is protected by the internal linear regulator, which ensures that V GATE_LS does not exceed the maximum V GS. Especially when working with the charge pump, the voltage at CP_OUT can be up to 65 V. The high-side gate is clamped internally in order to avoid a V GS exceeding 18 V.Gate protection does not include a fly-back voltage clamp that protects the driver and the external MOSFET from a fly-back voltage that can occur when driving inductive load. This fly-back voltage can reach high negative voltage values and needs to be clamped externally, as shown in Figure 12.Figure 12. Gate Protection and Flyback Voltage Clamp LOAD DUMP AND REVERSE BATTERYV CC and V CC2 can sustain load a dump pulse of 40 V and double battery of 24 V. Protection against reverse polarity is ensured by the external power MOSFET with the free-wheeling diodes forming a conducting pass from ground to V CC. Additional protection is not provided within the circuit. To protect the circuit an external diode can be put on the battery line. It is not recommended putting the diode on the ground line.TEMPERATURE PROTECTIONThere is temperature shutdown protection per each half-bridge. Temperature shutdown protects the circuitry against temperature damage by switching off the output drivers. Its typical value is 175°C with an hysteresis of 15°C.DV/DT AT V CCV CC voltage must be higher than (SRC_HS voltage minus a diode drop voltage) to avoid perturbation of the high-side driver.In some applications a large dV /d t at terminal C2 owing to sudden changes at V CC can cause large peak currents flowing through terminal C1, as shown in Figure 13.For positive transitions at terminal C2, the absolute value of the minimum peak current, I C1min, is specified at 2.0 A for a t C1min duration of 600 ns.For negative transitions at terminal C2, the maximum peak current, I C1max, is specified at 2.0 A for a t C1max duration of 600 ns. Current sourced by terminal C1 during a large dV /d t will result in a negative voltage at terminal C1 (Figure 13). The minimum peak voltage V C1min is specified at -1.5 V for a duration of t C1max = 600 ns. A series resistor with the charge pump capacitor (Ccp) capacitor can be added in order to limit the surge current.Output DriverOUTOutput Driver OUTINL1M2GATE_LSSRC_HSGATE_HSInductiveFlyback VoltageClampIND c l M1VCCCP_OUTLR_OUTV GS < 14 VUnder AllConditionsFUNCTIONAL DEVICE OPERATIONPROTECTION AND DIAGNOSTIC FEATURESFigure 13. Limits of C1 Current and Voltage with Large Values of dV/dtIn the case of rapidly changing V CC voltages, the large dV/dt may result in perturbations of the high-side driver, thereby forcing the driver into an OFF state. The addition ofcapacitors C3 and C4, as shown in Figure 14, reduces the dV/dt of the source line, consequently reducing driverperturbation. Typical values for R3 / R 4 and C3 / C 4 are 10 Ω and 10 nF, respectively.DV/DT AT V CC2When the external high-side MOSFET is on, in case of rapid negative change of V CC2 the voltage (V GATE_HS -V SRC_HS ) can be higher than the specified 18 V. In this case a resistance in the SRC line is necessary to limit the current to 5.0 mA max. It will protect the internal zener placed between GATE_HS and SRC terminals.In case of high current (SRC_HS >100 mA) and high voltage (>20 V) between GATE_HSX and SRC_HS an external zener of 18 V is needed as shown in Figure 14.t C1maxt C1minV CCI (C1+C2)I C1maxI C1minV (LR_OUT)0 VV (C1)0 AV C1minTYPICAL APPLICATIONSTYPICAL APPLICATIONSFigure 14.

LM138/LM3385-Amp Adjustable RegulatorsGeneral DescriptionThe LM138series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 5A over a 1.2V to 32V output range.They are exceptionally easy to use and require only 2resistors to set the output voltage.Careful circuit design has resulted in outstanding load and line regulation —comparable to many commercial power supplies.The LM138family is supplied in a standard 3-lead transistor package.A unique feature of the LM138family is time-dependent cur-rent limiting.The current limit circuitry allows peak currents of up to 12A to be drawn from the regulator for short periods of time.This allows the LM138to be used with heavy tran-sient loads and speeds start-up under full-load conditions.Under sustained loading conditions,the current limit de-creases to a safe value protecting the regulator.Also in-cluded on the chip are thermal overload protection and safe area protection for the power transistor.Overload protection remains functional even if the adjustment pin is accidentally disconnected.Normally,no capacitors are needed unless the device is situ-ated more than 6inches from the input filter capacitors in which case an input bypass is needed.An output capacitor can be added to improve transient response,while bypass-ing the adjustment pin will increase the regulator’s ripple re-jection.Besides replacing fixed regulators or discrete designs,the LM138is useful in a wide variety of other applications.Since the regulator is “floating”and sees only the input-to-output differential voltage,supplies of several hundred volts can be regulated as long as the maximum input to output differential is not exceeded,i.e.,do not short-circuit output to ground.The part numbers in the LM138series which have a K suffix are packaged in a standard Steel TO-3package,while those with a T suffix are packaged in a TO-220plastic package.The LM138is rated for −55˚C ≤T J ≤+150˚C,and the LM338is rated for 0˚C ≤T J ≤+125˚C.Featuresn Guaranteed 7A peak output current n Guaranteed 5A output current n Adjustable output down to 1.2V n Guaranteed thermal regulationn Current limit

adjustment terminal.The reference voltage is impressed across program resistor R1and,since the voltage is constant,a constant current I 1then flows through the output set resistor R2,giving an out-put voltage ofTemperature StabilityDS009060-38Output ImpedanceDS009060-39Minimum Operating CurrentDS009060-40Ripple Rejection DS009060-41Ripple Rejection DS009060-42Ripple RejectionDS009060-43Line Transient Response DS009060-44Load Transient ResponseDS009060-45 4Application Hints(Continued)Since the 50µA current from the adjustment terminal repre-sents an error term,the LM138was designed to minimize I ADJ and make it very constant with line and load changes.To do this,all quiescent operating current is returned to the output establishing a minimum load current requirement.If there is insufficient load on the output,the output will rise.External CapacitorsAn input bypass capacitor is recommended.A 0.1µF disc or 1µF solid tantalum on the input is suitable input bypassing for almost all applications.The device is more sensitive to the absence of input bypassiing when adjustment or output capacitors are used but the above values will eliminate the possiblity of problems.The adjustment terminal can be bypassed to ground on the LM138to improve ripple rejection.This bypass capacitor prevents ripple from being amplified as the output voltage is increased.With a 10µF bypass capacitor 75dB ripple rejec-tion is obtainable at any output level.Increases over 20µF do not appreciably improve the ripple rejection at frequen-cies above 120Hz.If the bypass capacitor is used,it is sometimes necessary to include protection diodes to prevent the capacitor from discharging through internal low current paths and damaging the device.In general,the best type of capacitors to use are solid tanta-lum.Solid tantalum capacitors have low impedance even at high frequencies.Depending upon capacitor construction,it takes about 25µF in aluminum electrolytic to equal 1µF solid tantalum at high frequencies.Ceramic capacitors are also good at high frequencies;but some types have a large decrease in capacitance at frequencies around 0.5MHz.For this reason,0.01µF disc may seem to work better than a 0.1µF disc as a bypass.Although the LM138is stable with no output capacitors,like any feedback circuit,certain values of external capacitance can cause excessive ringing.This occurs with values be-tween 500pF and 5000pF.A 1µF solid tantalum (or 25µF aluminum electrolytic)on the output swamps this effect and insures stability.Load RegulationThe LM138is capable of providing extremely good load regulation but a few precautions are needed to obtain maxi-mum performance.The current set resistor connected be-tween the adjustment terminal and the output terminal (usu-ally 240Ω)should be tied directly to the output of the regulator (case)rather than near the load.This eliminates line drops from appearing effectively in series with the refer-ence and degrading regulation.For example,a 15V regula-tor with 0.05Ωresistance between the regulator and load will have a load regulation due to line resistance of 0.05Ωx I L .If the set resistor is connected near the load the effective line resistance will be 0.05Ω(1+R2/R1)or in this case,11.5times worse.Figure 2shows the effect of resistance between the regula-tor and 240Ωset resistor.With the TO-3package,it is easy to minimize the resistance from the case to the set resistor,by using 2separate leads to the case.The ground of R2can be returned near the ground of the load to provide remote ground sensing and improve load regulation.Protection DiodesWhen external capacitors are used with any IC regulator it is sometimes necessary to add protection diodes to prevent the capacitors from discharging through low current points into the regulator.Most 20µF capacitors have low enough internal series resistance to deliver 20A spikes when shorted.Although the surge is short,there is enough energy to damage parts of the IC.When an output capacitor is connected to a regulator and the input is shorted,the output capacitor will discharge into the output of the regulator.The discharge current depends on the value of the capacitor,the output voltage of the regu-lator,and the rate of decrease of V IN .In the LM138this dis-charge path is through a large junction that is able to sustain 25A surge with no problem.This is not true of other types of positive regulators.For output capacitors of 100µF or less at output of 15V or less,there is no need to use diodes.The bypass capacitor on the adjustment terminal can dis-charge through a low current junction.Discharge occurs when either the input or output is shorted.Internal to the LM138is a 50Ωresistor which limits the peak discharge cur-rent.No protection is needed for output voltages of 25V or less and 10µF capacitance.Figure 3shows an LM138with protection diodes included for use with outputs greater than 25V and high values of output capacitance.DS009060-6FIGURE 1.DS009060-7FIGURE 2.Regulator with Line Resistance in Output Lead5Application Hints(Continued)DS009060-8D1protects against C1D2protects against C2FIGURE3.Regulator with

MAXIM MAX338 MAX339 数据手册

The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ωmax, and the devices conduct current equally well in both directions.These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resis-tance, see the MAX328 and MAX329.The MAX338/MAX339 operate from a single +4.5V to +30V supply or from dual supplies of ±4.5V to ±20V.All control inputs (whether address or enable) are TTL compatible (+0.8V to +2.4V) over the full specified tem-perature range and over the ±4.5V to ±18V supply range. These parts are fabricated with Maxim’s 44V sili-con-gate process.________________________ApplicationsData-Acquisition Systems Sample-and-Hold Circuits Test Equipment Heads-Up Displays Military RadiosCommunications Systems Guidance and Control SystemsPBX, PABX____________________________Features♦On-Resistance, <400Ωmax ♦Transition Time, <500ns ♦On-Resistance Match, <10Ω♦NO-Off Leakage Current, <20pA at +25°C ♦1.5pC Charge Injection♦Single-Supply Operation (+4.5V to +30V)Bipolar-Supply Operation (±4.5V to ±20V)♦Plug-In Upgrade for Industry-Standard DG508A/DG509A ♦Rail-to-Rail Signal Handling ♦TTL/CMOS-Logic Compatible♦ESD Protection >2000V, per Method 3015.7Ordering InformationMAX338/MAX3398-Channel/Dual 4-Channel,Low-Leakage, CMOS Analog Multiplexers________________________________________________________________Maxim Integrated Products 1_____________________Pin Configurations/Functional Diagrams/Truth Tables19-0272; Rev 3; 11/04Ordering Information continued at end of data sheet.*Contact factory for dice specifications.**Contact factory for availability.For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .General DescriptionM A X 338/M A X 3398-Channel/Dual 4-Channel,Low-Leakage, CMOS Analog Multiplexers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—Dual Supplies(V+ = +15V, V- = -15V, GND = 0V, V AH = +2.4V, V AL = +0.8V, T A = T MIN to T MAX , unless otherwise noted.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The MAX338/MAX339 switches operate with ±4.5V to ±20V bipolar supplies or with a +4.5V to +30V single supply. Connect V- to GND when operating with a single supply. Both device types can also operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)Overvoltage ProtectionProper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings, because stresses beyond the listed rat-ings may cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by the logic inputs NO and COM. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1).Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but does not affect the devices’ low switch resistance and low leakage charac-teristics. Device operation is unchanged, and the differ-ence between V+ and V- should not exceed 44V.M A X 338/M A X 3398-Channel/Dual 4-Channel,Low-Leakage, CMOS Analog Multiplexers 6_____________________________________________________________________________________________________________________________________________________Pin DescriptionFigure 1.
