February 2006

MCT6, MCT61, MCT62 Dual Phototransistor Optocouplers
Features

Description
The MCT6X Optocouplers have two channels for density applications. For four channel applications, two-packages fit into a standard 16-pin DIP socket. Each channel is an NPN silicon planar phototransistor optically coupled to a gallium arsenide infrared emitting diode.

Two isolated channels per package Two packages fit into a 16 lead DIP socket Choice of three current transfer ratios Underwriters Laboratory (U.L.) recognized File E90700
