6N137 SMD High Speed Opto-coupler

The 6N137-SMD is single channel 10 MBd opto-coupler utilizing a high efficient input LED coupled with an integrated optical photodiode IC detector.

The detector has an open drain NMOS-transistor output, providing less leakage compared to an open collector Schottky clamped transistor output. For the single channel type, an enable function on pin 7 allows the detector to be strobed. The use of a 0.1 μF bypass capacitor connected between pin 5 and 8 is recommended.
