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.
