Description

The 6N138M/9M and HCPL2730M/31M optocouplers

consist of an AlGaAs LED optically coupled to a high

gain split darlington photodetector.

The split darlington confifiguration separating the input

photodiode and the fifirst stage gain from the output

transistor permits lower output saturation voltage and

higher speed operation than possible with conventional

darlington phototransistor optocoupler. In the dual

channel devices, HCPL2730M/HCPL2731M, an integrated emitter-base resistor provides superior stability

over temperature.

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.
