6N139
Abstract: design ideas opto coupling transistor optoisolator TTL 4.7M resistor 6N138 application
Contextual Info: LOW CURRENT INPUT CIRCUIT IDEAS 6N138/139 SERIES Advancements in opto-coupling and LED technology have given us the 6N139. This unique optocoupler, having an input LED current specification at 500 microamperes, has opened some interesting design doors. Besides the obvious and much written about
