DESCRIPTION
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 TTL.
This optocoupler is constructed in a standard SOIC-8 foot print which makes it ideally suited for high density applications. In addition to eliminating through-hole requirements, this package conforms to standards for surface mount devices.
