Description
The IL256A is an AC input phototransistor optocoupler. The device consists of two infrared emitters connected in reverse parallel and coupled to a silicon NPN phototransistor detector.
These circuit elements are constructed with a standard SOIC-8 foot print.
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) minimum of 20 % at IF = 10 mA.

FEATUREs
• Guaranteed CTR Symmetry, 2:1 Maximum
• Bidirectional AC Input Industry Standard SOIC-8
   Surface Mountable Package
• Standard Lead Spacing, .05 "
• Available only on Tape and Reel (Conform to EIA Standard RS481A)

APPLICATIONs
   Telecom applications ring detection
