DESCRIPTION
The ILD223 is a high current transfer ratio (CTR)
optocoupler . It has a Gallium Arsenide infrared LED
emitter and a silicon NPN photodarlington transistor detector.
This device has CTRs tested at an LED current of
1 mA. This low drive current permits easy interfacing 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-
