6N139 Overview
These high gain series couplers use a Light Emitting Diode and an integrated high gain photodetector to provide extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage result in TTL patible saturation voltages and high speed operation. Where desired the VCC and VO terminals may be tied together to achieve conventional photodarlington operation.
