6N138 6N139
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.
