DESCRIPTION
=1 mA,
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.
