IL221AT Datasheet (Vishay)

IL221AT, Optocoupler

The IL221AT/IL222AT/IL223AT is a high current transfer ratio (CTR) optocoupler with a gallium arsenide infrared LED emitter and a silicon NPN photodarlington transistor detector.

The device has a CTR tested at 1.0 mA LED current.

This low drive current permits easy interfacing from CMOS to LSTTL or
