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. Input Current Threshold : IF=5mA(Max.) Switching Speed : 10MBd(TYP ,@NRZ) Common mode transient immunity : ±1000V/us(Min) Guaranteed PerformanceOverTemperature : 0~70°C Isolation Voltage : 2500Vrms(Min) UL Recognized :UL1577,File No.E67349
