Description

The 6N138 & 6N139 optocouplers consist of an

AlGaAs LED optically coupled to a high gain split

darlington photodetector.

The combination of a very low input current of

0.5mA and a high current transfer ratio of 2000%

makes this family particularly useful for input

interface to MOS, CMOS, LSTTL and EIA RS232C,

while output compatibility is ensured to CMOS as

well as high fan-out TTL requirements.

The devices are packaged in an 8-pin DIP package

and also available in gullwing (400mil) spacing and

surface mount lead forming option.
