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
