Description
The 6N138/9 and HCPL-2730/HCPL-2731 optocouplers consist
of an AlGaAs LED optically coupled to a high gain split darling-
ton photodetector.
The split darlington configuration separating the input photo-
diode and the first stage gain from the output transistor permits
lower output saturation voltage and higher speed operation than
possible with conventional darlington phototransistor optocou-
pler. In the dual channel devices, HCPL-2730/HCPL2731, an
integrated emitter - base resistor provides superior stability over
temperature.
The combination of a very low input current of 0.5 mA and a
high current transfer ratio of 2000% makes this family particu-
larly 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 pro-
vides exceptional common mode rejection of 10 kV/µs.
