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.
