HCPL2731WV Datasheet

High Speed Optocouplers


The 6N138/9 and HCPL2731WV optocouplers consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector.The split darlington conguration separating the input photodiode and the rst stage gain from the output transistor permits lower output saturation voltage higher speed operation than possible with conventional darlington phototransistor optocoupler. In the dual channel devices, HCPL2731WV, 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 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. HCPL2731WV Features • Low current – 0.5mA• Superior CTR-2000%• Superior CMR-10kV/µs • CTR guaranteed 0–70°C• U.L. recognized (File # E90700)• VDE recognized (File # 120915) Ordering option V, e.g., 6N138V• Dual Channel – HCPL2730, HCPL2731 HCPL2731WV Applications • Digital logic ground isolation • Telephone ring detector• EIA-RS-232C line receiver• High common mode noise line receiver• µP bus isolation• Current loop receiver
