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.
