Product Description

Product Overview

The IL221AT/IL222AT/IL223AT is a high current transfer ratio (CTR) optocoupler featuring a gallium arsenide infrared LED emitter and a silicon NPN photodarlington transistor detector. Designed for low input current applications, it offers high gain and a base connection for added flexibility. Its SOIC-8 surface mountable package is ideal for high-density applications and conforms to standards for surface mount devices. This optocoupler is suitable for interfacing from CMOS to LSTTL or TTL.
