MCT9001

DESCRIPTION

The MCT9001 Optocoupler has 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.

FEATURES

•Two isolated channels per package

•Two packages fit into a 16 lead DIP socket

• Underwriters Laboratory (U.L.) recognized File E90700

APPLICATIONS

•AC Line/Digital Logic - isolate high voltage transients

• Digital Logic/Digital Logic - Eliminate spurious grounds

• Digital Logic/AC Triac Control - isolate high voltage transients

•Twisted pair line receiver - Eliminate ground loop feedthrough

•Telephone/Telegraph line receiver - isolate high voltage transients

• High Frequency Power Supply Feedback Control - Maintain floating grounds and
transients

• Relay contact monitor - isolate floating grounds and transients

•Power supply monitor - Isolate transients
