DESCRIPTION

These diode-transistor photocouplers

consist of an AlGaAs LED optically

coupled to a high speed photodetector.

The output features is an open collector

and coupler parameters are guaranteed

over the temperature range from

-40℃~85℃. The internal shield

provides a guaranteed Common Mode

Transient Immunity (typical) 10KV/

μs

FEATURES

* High speed – 10MBd

* Common mode rejection - 10KV/

μs
