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.

This device has a CTR tested at an 1 mA LED

current. This low drive current permits easy interfac-

ing 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-holes requirements, this package conforms

to standards for surface mounted devices.
