8 PIN DIP HIGH SPEED SPLIT DARLINGTON
PHOTOCOUPLER
6N138 6N139
Features:
• High isolation voltage between input
and output (Viso=5000 Vrms )
• Guaranteed performance from 0°C to 70°C
• Pb free and RoHS compliant.
Description
The 6N138 and 6N139 devices each consists of an infrared
emitting diodes, optically coupled to a high gain split Darlington
photo detectors.
They are packaged in an 8-pin DIP package and
available in wide-lead spacing and SMD options.
Applications
Schematic
• Digital logic ground isolation
• RS-232C line receiver
• High common mode noise line receiver
• Microprocessor bus isolation
• Current loop receiver
