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.
