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 conï¬guration separating the input
photodiode and the ï¬rst 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 inte-
grated 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 compati-
bility is ensured to CMOS as well as high fan-out TTL
requirements. An internal noise shield provides excep-
tional common mode rejection of 10 kV/µs.
