IS657C
ISO - LOGIC INVERTER
SCHMITT TRIGGER SIDE
DETECTOR
Dimensions in mm
DESCRIPTION
The IS657C is an optically integrated
circuit detector with schmitt trigger inverter
output. It is mounted in a clear plastic lateral
side looking package which enables these
devices to display superior mechanical
resolutions, coupled characteristics and
reliability in a low cost housing.
