DESCRIPTION

The IL256A is an AC input phototransistor optocou- pler. 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 stan- dard 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 I F = 10 mA.
