DESCRIPTION

The IL221A/IL222A/IL223A is a high current trans-

fer ratio (CTR) optocoupler with a Gallium Arsenide

infrared LED emitter and a silicon NPN photodar-

lington transistor detector.

This device has a CTR tested at an 1 mA LED cur-

rent. 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-holes requirements, this package con-

forms to standards for surface mounted devices.
