Single-Channel: 6N138, 6N139 Dual-Channel: HCPL2730, HCPL2731 Low Input Current High Gain Split Darlington Optocouplers August 2008 Single-Channel: 6N138, 6N139 Dual-Channel: HCPL2730, HCPL2731 Low Input Current High Gain Split Darlington Optocouplers Features Description Low current 0.5mA The 6N138/9 and HCPL2730/HCPL2731 optocouplers consist of an AlGaAs LED optically coupled to a high Superior CTR-2000% gain split darlington photodetector. Superior CMR-10kV/s The split darlington conguration separating the input CTR guaranteed 070C photodiode and the rst stage gain from the output U.L. recognized (File E90700) transistor permits lower output saturation voltage and VDE recognized (File 120915) Ordering option V, higher speed operation than possible with conventional e.g., 6N138V darlington phototransistor optocoupler. In the dual Dual Channel HCPL2730, HCPL2731 channel devices, HCPL2730/HCPL2731, an integrated emitter-base resistor provides superior stability over Applications temperature. Digital logic ground isolation The combination of a very low input current of 0.5mA Telephone ring detector and a high current transfer ratio of 2000% makes this EIA-RS-232C line receiver family particularly useful for input interface to MOS, CMOS, LSTTL and EIA RS232C, while output compati- High common mode noise line receiver bility is ensured to CMOS as well as high fan-out TTL P bus isolation requirements. An internal noise shield provides excep- Current loop receiver tional common mode rejection of 10 kV/s.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
