DESCRIPTION
The IL256AT 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 tele applications such as ring detection or off / on hook status, given its bidirectional LED input and...
