OPTOCOUPLERS

DESCRIPTION

The CNW138 and CNW139 are high isolation voltage optocouplers, comprising an

infrared emitting AlGaAs diode, optically coupled to a high gain split Darlington

photodetector in an 8-pin wide body dual-in-line package (DIP).

APPLICATIONS

• Line receivers

• Logic families ground isolation

• Low power systems

• Line voltage status indicator.
