MCT6, MCT61, MCT62

8-Pin Dual Channel Phototransistor Optocouplers

Features

• Two Isolated Channels Per Package

• Safety and Regulatory Approvals:

– UL1577, 5,000 VACRMS for 1 Minute

– DIN-EN/IEC60747-5-5, 890 V Peak Working

Insulation Voltage

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

Description

The general purpose optocouplers, MCT6, MCT61, and

MCT62, have two isolated channels in a standard plastic

8-pin dual-in-line (DIP) package for density applications.

Each channel consists of a gallium arsenide infrared

emitting diode driving a NPN silicon planar

phototransistor. For four channel applications, two

packages fit into a standard 16-pin DIP socket.
