ISOLATED LINE RECEIVER SIMPLEX/MULTIPLEX DATA TRANSMISSION COMPUTER-PERIPHERAL INTERFACE MICROPROCESSOR SYSTEM INTERFACES DIGITAL ISOLATION FOR A/D,D/A CONVERSION
The TOSHIBA TLP554 a photocoupler which combines a GaAlAsIRED as the emitter and an integrated high gain,high speed photodetector. The output of the detector circuit is an open collector,Schottky Clamped transistor. A Faraday shield integrated on the photodetector chip reduces the effects of capacitive coupling between the input LED emitter and the high gain stages of the detector. This provides an effective common mode transient immunity of 1000V/us. l l l l l l Input Current Threshold Switching Speed Common mode transient immunity Guaranteed PerformanceOverTemperature Isolation Voltage UL Recognized : IF=5mA(Max.) : 10MBd(TYP,@NRZ) : 1000V/us(Min) : 0~70C : 2500Vrms(Min) :UL1577,File No.E67349 Unit: mm

(Note 1) The VCC supply voltage to each TLP554 isolator must be bypassed by a 0.1mF capacitor or larger.This can be either a ceramic or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible to the package VCC and GND pins each device. (Note 2) 1 Minute Maximum. (Note 3) Not to exceed VCC by more than 500mV. (Note 4) 2mm below seating plane. (Note 5) Device considered a two-terminal device :Pins 1,2,3 and 4 shorted together,and Pins 5, 6,7 and 8 shorted together.
