1 / 12 page FEATURES • Low current - 0.5 mA • Superior CTR-2000% • Superior CMR-10 kV/µs • Double working voltage-480V RMS • CTR guaranteed 0-70°C • U.L. recognized (File # E90700) • Dual Channel - HCPL-2730 HCPL-2731 LOW INPUT CURRENT HIGH GAIN SPLIT DARLINGTON OPTOCOUPLERS DESCRIPTION The 6N138/9 and HCPL-2730/HCPL-2731 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, 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 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. An improved package allows superior insulation permitting a 480 V working voltage compared to industry standard 220 V.
