About this product
The 6N138 is a DIP-8 optocoupler with a high-gain Darlington output and low input current. It isolates logic signals between circuits operating at different voltages or grounds, with 5300 VRMS isolation, so it suits interfacing microcontrollers with higher-voltage or noisy circuits.

Which pins are the input and output?
The input LED uses pin 2 (anode) and pin 3 (cathode). The output uses pin 6 (output), pin 5 (GND) and pin 8 (VCC). Pin 7 (base) is normally left unconnected. Verify against the datasheet for your exact revision.
Does the output need a pull-up resistor?
Yes. The Darlington output acts as a switch to ground, so a pull-up resistor from VCC (pin 8) to the output (pin 6) is required to produce a logic-high level when the LED is off.
