ILD256 General Description

The ILD256 is a dual channel optocoupler. Each channel consists of two infrared emitters connected in anti-parallel and coupled to a silicon NPN phototransistor detector.

These circuit elements are constructed with a standard SOIC-8 footprint.

The product is well suited for telecom applications such as ring detection or off/on hook status, given its bidirectional LED input and guaranteed current transfer ratio (CTR) of 20% at I_F= 10 mA.

ILD256 Maximum Ratings

Continuous Forward Current .................30 mA
Power Dissipation at 25°C...................45 mW
Derate Linearly from 25°C............0.5 mW/°C

ILD256 Features

• Each Channel: Guaranteed CTR Symmetry, 2:1 Maximum
• Bidirectional AC Input
• Industry Standard SOIC-8 Surface Mountable Package
• Standard Lead Spacing, .05"
• Available in Tape and Reel Option (Conforms to EIA Standard 481-2)
