DUAL PHOTOTRANSISTOR
OPTOCOUPLERS
MCT6
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.
