Optocoupler, Photodarlington Output, Low Input Current,

High Gain, with Base Connection

DESCRIPTION

The VO221AT, VO222AT, VO223AT are high current transfer

ratio (CTR) optocouplers with a gallium arsenide infrared

LED emitter and a silicon NPN photodarlington transistor

detector.

The device has a CTR tested at 1 mA LED current. This low

drive current permits easy interfacing from CMOS to LSTTL

or TTL.
