MCT6 MCT61 MCT62

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.

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
