Description
The 6N138/9 and HCPL2730/HCPL2731 optocouplers
consist of an AlGaAs LED optically coupled to a high
gain split darlington photodetector.
The split darlington configuration separating the input
photodiode and the first 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, HCPL2730/HCPL2731, 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 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.
