PHOTOCOUPLER
PS9821-1,-2
HIGH CMR, 15 Mbps OPEN COLLECTOR OUTPUT TYPE
8-PIN SSOP (SO-8)
−NEPOC
3.3 V HIGH-SPEED PHOTOCOUPLER
DESCRIPTION
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 mode transient immunity (CMR) and low pulse width
distortion, PS9821-2 is suitable for high density applications.
