802256 6N138 - Optocoupler

6N138 Optocoupler. 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. An internal noise shield provides exceptional common mode rejection of 10 kV/μs.
