• CSA approved (No. 2037145)
Description
The 6N138 and 6N139 devices each consists of an infrared
emitting diode, optically coupled to a high gain split Darlington
photo detector. They provide extremely high current transfer
ratio between input and output, with access to a base terminal
to adjust the gain bandwidth.
These devices are packaged in an 8-pin DIP package
and available in wide-lead spacing and SMD options.
Applications
• Digital logic ground isolation
• RS-232C line receiver
• Low input current line receiver
• Microprocessor bus isolation
• Current loop receiver
