IL222AT Optocoupler, Photodarlington Output, Low Input Current, High Gain, With Base Connection

* oTheIL221AT, IL222AT, IL223AT are high current transfer ratio (CTR) optocouplers with a gallium arsenide infrared  LED emitter and a silicon NPN photodarlington transistor detector.

* oThedevice has a CTR tested at 1.0 mA LED current. This low drive current permits easy interfacing from CMOS to LSTTL or TTL.

* oThisoptocoupler 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.
