DESCRIPTION
The ILD223T 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
1.0 mA. This low drive current permits easy inter-
facing from CMOS to LSTTL or TTL.
The ILD223T is constructed in a standard SOIC-8A
foot print which makes it ideally suited for high density applications. In addition to eliminating throughholes requirements, this package conforms to standards for surface mounted devices.
