Tel: 886-2-2222-6181 Fax: 886-2-2221-1948 / 886-2-2221-0660 LITE-ON TECHNOLOGY CORPORATION Property of Lite-on Only 6N138, 6N139 Single Channel, High Speed Optocouplers Dec.2008 Description 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 Features photo darlington operation. A base access High current transfer ratio 2000% terminal allows a gain bandwidth adjustment typical. to be made. Low input current requirements 0.5mA Functional Diagram High output current 60mA CTR guarantee 0~70.
