IL256A

IL256A EW FEATURES Guranteed 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 RS481A) DESCRIPTION The IL256A is an AC input phototransistor optocoupler. The device 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 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.
