Broadcom, 6N139-000E DC Input Phototransistor Output Optocoupler, Through Hole, 8-Pin DIP

This range of optocouplers with darlington output, from Avago Technologies, offer a high current transfer ratio with low input current requirements. The optocoupler devices use light emitting diodes (LEDs) optically coupled with integrated high gain photodetectors. They provide excellent input-output common mode transient immunity and guaranteed performance over temperatures of 0 to 70°C.

Potential applications include:
ground isolate most logic families
low input current line receiver
EIA RS-232C line receiver
telephone ring detector
line voltage status indicator – low input power dissipation
