Used in conjunction with isolated power supplies,these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.The devices have TTL input thresholds and can operate from2.7V,3.3V and5V supplies.All inputs are5V tolerant when supplied from3.3V or2.7V supplies.PIN DESCRIPTIONSPINI/O DESCRIPTIONNAME ISO7640ISO7641INA33I Input,channel AINB44I Input,channel BINC55I Input,channel CIND611I Input,channel DOUTA1414O Output,channel AOUTB1313O Output,channel BOUTC1212O Output,channel COUTD116O Output,channel DEnables(when input is High or Open)or Disables(when input is Low)OUTA,OUTB,OUTC EN10-Iand OUTD of ISO7640EN1-7I Enables(when input is High or Open)or Disables(when input is Low)OUTD of ISO7641Enables(when input is High or Open)or Disables(when input is Low)OUTA,OUTB,andEN2-10IOUTC of ISO7641V CC111–Power supply,V CC1V CC21616–Power supply,V CC2GND12,82,8–Ground connection for V CC1GND29,159,15–Ground connection for V CC2NC7--No Connect pins are floating with no internal connectionTable1.FUNCTION TABLE(1)INPUT OUTPUT INPUT OUTPUT ENABLE OUTPUTV CC V CC(INx)(ENx)(OUTx)H H or Open HL H or Open LPU PUX L ZOpen H or Open LPD PU X H or Open LPD PU X L ZPU PD X X Z(1)PU=Powered Up(V CC≥2.7V);PD=Powered Down(V CC≤2.1V);X=Irrelevant;H=High Level;L=Low Level;Z=High Impedance2Submit Documentation Feedback Copyright©2011–2012,Texas Instruments IncorporatedISO7640FMISO7641FM SLLSE89D–SEPTEMBER2011–REVISED JULY2012AVAILABLE OPTIONSRATED INPUT DATA RATE CHANNEL MARKED ORDERING PRODUCT PACKAGEISOLATION THRESHOLD and FILTER DIRECTION AS NUMBERISO7640FMDW(rail)4Forward,ISO7640FM ISO7640FM0Reverse1.5V TTL ISO7640FMDWR(reel)6KV PK/150Mbps,DW-16(CMOS5KV RMS(1)No Noise Filter ISO7641FMDW(rail)Compatible)3Forward,ISO7641FM ISO7641FM1Reverse ISO7641FMDWR(reel) (1)See the Regulatory Information table for detailed isolation ratings.ABSOLUTE MAXIMUM RATINGS(1)VALUE PARAMETER UNITMIN MAXSupply voltage(2)V CC1,V CC2–0.56VVoltage INx,OUTx,ENx–0.56VOutput Current,I O±15mAHuman Body Model ESDA,JEDEC JS-001-2012±4kVField-Induced Charged DeviceElectrostatic discharge JEDEC JESD22-C101E All pins±1.5kV ModelMachine Model JEDEC JESD22-A115-A±200VMaximum junction temperature,T J150°CStorage temperature,T STG-65150°C (1)Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device.These are stress ratingsonly and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied.Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.(2)All voltage values except differential I/O bus voltages are with respect to the local ground terminal(GND1or GND2)and are peakvoltage values.RECOMMENDED OPERATING CONDITIONSPARAMETER MIN TYP MAX UNITSupply voltage V CC1,V CC2 2.7 5.5VHigh-level output current I OH-4mALow-level output current I OL4mAHigh-level input voltage V IH2V CC VLow-level input voltage V IL00.8V≥3V-Operation 6.67Input pulse duration t ui ns<3V-Operation10≥3V-Operation0150Signaling rate1/t ui Mbps<3V-Operation0100Junction temperature T J-40136°CAmbient temperature T A-4025125°C Copyright©2011–2012,Texas Instruments Incorporated Submit Documentation Feedback3ISO7640FMISO7641FMSLLSE89D–SEPTEMBER2011–REVISED THERMAL INFORMATIONISO76xxTHERMAL METRIC(1)UNITSDW(16Pins)θJA Junction-to-ambient thermal resistance72θJC(top)Junction-to-case(top)thermal resistance38θJB Junction-to-board thermal resistance39°C/WψJT Junction-to-top characterization parameter9.4ψJB Junction-to-board characterization parameter n/aθJC(bottom)Junction-to-case(bottom)thermal resistance n/aV CC1=V CC2=5.5V,T J=150°C,C L=15pFP D Maximum Device Power Dissipation399mWInput a75MHz50%duty cycle square wave(1)For more information about traditional and new thermal metrics,see the IC Package Thermal Metrics application report,SPRA953.

RMS for1second in accordance with UL1577.IEC SAFETY LIMITING VALUESSafety limiting intends to prevent potential damage to the isolation barrier upon failure of input or output circuitry.A failure of the IO can allow low resistance to ground or the supply and,without current limiting,dissipate sufficient power to overheat the die and damage the isolation barrier potentially leading to secondary system failures.PARAMETER TEST CONDITIONS MIN TYP MAX UNITθJA=72°C/W,V I=5.5V,T J=150°C,T A=25°C316 Safety input,output,or supplyI S DW-16θJA=72°C/W,V I=3.6V,T J=150°C,T A=25°C482mAcurrentθJA=72°C/W,V I=2.7V,T J=150°C,T A=25°C643T S Maximum case temperature150°C The safety-limiting constraint is the absolute maximum junction temperature specified in the absolute maximum ratings table.The power dissipation and junction-to-air thermal impedance of the device installed in the application hardware determines the junction temperature.The assumed junction-to-air thermal resistance in the Thermal Information table is that of a device installed on a High-K Test Board for Leaded Surface Mount Packages.The power is the recommended maximum input voltage times the current.The junction temperature is then the ambient temperature plus the power times the junction-to-air thermal resistance.。
