VO221AT Datasheet (Vishay)

VO221AT, Optocoupler

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
