This diode-transistor photocouplers consist of an LED, optically coupled to a high speed photodetector to transmit electrical signals between circuits while still isolating your system from higher voltages. The 6N137 optoisolator is presented in an 8-pin DIP package.

The output features is an open collector and coupler parameters are guaranteed over the temperature range from -40℃~5℃. The internal shield provides a guaranteed Common Mode Transient Immunity (typical) 10 KV/μs.
