PS9821-1 Datasheet (CEL)

PS9821-1, PHOTOCOUPLER

The PS9821-1 and PS9821-2 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 PS9821-1, -2 are designed specifically for high common mod
