• Power supply monitor – isolate transients
Description
The general purpose optocoupler, MCT9001, has two
isolated channels in a standard plastic 8-pin dual-in-line
(DIP) package for density applications. Each channel
consists of a gallium arsenide infrared emitting diode
driving a NPN silicon planar phototransistor. For four
channel applications, two packages fit into a standard
16-pin DIP socket.
