NEC's HIGH CMR ,
10 Mbps OPEN COLLECTOR
PS9814-1,-2
OUTPUT TYPE 8-PIN SSOP (SO-8)
HIGH-SPEED OPTOCOUPLER
DESCRIPTION
NEC's PS9814-1 and PS9814-2 are active-low type high-
speed optocouplers 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 PS9814-1, -2 are designed specifically for high
common mode transient immunity (CMR) and low pulse
width distortion, the PS9814-2 is suitable for high density
applications.
