DESCRIPTION

The SFH691AT has a GaAs infrared emitting diode emitter,

which is optically coupled to silicon planar phototransistor

detector, and is incorporated in a 4 pin 100 mil lead pitch

miniflat package. It features a high current transfer ratio, low

coupling capacitance, and high isolation voltage.

The coupling devices are designed for signal transmission

between two electrically separated circuits.
