| ILD223T Dual Photodarlington Small Outline Surface Mount Optocoupler FEATURES * Two Channel Optocoupler * High Current Transfer Ratio at IF=1.0 mA, 500% Min. * Isolation Test Voltage, 3000 VRMS * Electrical Specifications Similar to Standard 6-pin Coupler * Compatible with Dual Wave, Vapor Phase and IR Reflow Soldering * SOIC-8 Surface Mountable Package * Standard Lead Spacing, .05" * Available only on Tape and Reel Option (Conforms to EIA Standard 481-2) * Underwriters Lab File #E52744 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 interfacing 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.
