MCT6, MCT61, MCT62
Dual Phototransistor Optocouplers
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
■
VDE approved for IEC60747-5-2
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.
Applications
■
AC line/digital logic – isolate high voltage transients
■
Digital logic/digital logic – eliminate spurious grounds
■
Digital logic/AC triac control – isolate high voltage
