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.
