LITE-ON TECHNOLOGY CORPORATION Property of Lite-on Only 6N138, 6N139 Single Channel, High Speed Optocouplers Description Dec.2008 These high gain series couplers use a light emitter diode and an integrated high gain photo detector to provide extremely high current transfer ratio between input and output. Separate pins for the photodiode and output stage result in TTL compatible saturation voltage and high speed operation. Where desired the Vcc and Vo terminals may be tied together to achieve conventional photo darlington operation. A base access terminal allows a gain bandwidth adjustment to be made. Functional Diagram NC ANODE Cathode VCC VB VO Features • High current transfer ratio – 2000% typical. • Low input current requirements – 0.
