The MOC256 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. They are designed for applications requiring the detection or monitoring of AC signals. These devices are constructed with a standard SOIC–8 footprint.
