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.
