MOC256-M
DESCRIPTION
The MOC256-M is an AC input phototransistor optocoupler. The device consists of two infra-
red emitters connected in anti-parallel and coupled to a silicon NPN phototransistor detector.
It is designed for applications requiring the detection or monitoring of AC signals. The device
is constructed with a standard SOIC-8 footprint.
