DESCRIPTION
F
=1 mA,
The ILD223 is a high current transfer ratio (CTR)
optocoupler. It has a Gallium Arsenide infrared LED
emitter and a silicon NPN photodarlington transis-
tor detector.
This device has CTRs tested at an LED current of
1 mA. This low drive current permits easy interfac-
ing from CMOS to LSTTL or TTL.
The ILD223 is constructed in a standard SOIC-8
foot print which makes it ideally suited for high den-
sity applications. In addition to eliminating through-
holes requirements, this package conforms to stan-
dards for surface mounted devices.
