H11F3M Datasheet PDF - Fairchild

General Description

●The H11FXM series consists of a Gallium-Aluminum Arsenide IRED emitting diode coupled to a symmetrical bilateral silicon photo-detector. The detector is electrically isolated from the input and performs like an ideal isolated FET designed for distortion-free control of low level AC and DC analog signals. The H11FXM series devices are mounted in dual in-line packages.
