MCT62.300 - Fairchild Semiconductor Corporation

DESCRIPTION

The MCT6X Optocouplers have two channels for density applica-

tions. For four channel applications, two-packages fit into a standard

16-pin DIP socket. Each channel is an NPN silicon planar phototran-

sistor optically coupled to a gallium arsenide infrared emitting diode.

FEATURES

• 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

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
