DESCRIPTION

The IS657B is an optically integrated
circuit detector with schmitt trigger open
collector buffer 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.

FEATURES

l Built-in Schmitt trigger circuit

l High level output at incident light

l Open collector output

l Lateral Side Looking Plastic Package

l High Sensitivity (E

V
