DESCRIPTION
The PS9817A-1 and PS9817A-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting
diode on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on
the output side.
The PS9817A-1 and PS9817A-2 are designed specifically for high common mode transient immunity (CMR) and
low pulse width distortion. The PS9817A-2 is suitable for high density applications.
