6N139SM

双通道： HCPL2730M ， HCPL2731M （初步）低输入电流，高增益分裂达林顿光电耦合器 Dual-Channel: HCPL2730M, HCPL2731M Preliminary Low Input Current High Gain Split Darlington Optocouplers

Description

The 6N138M/9M and HCPL2730M/31M 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, HCPL2730M/HCPL2731M, an integrated emitter-base resistor provides superior stability over temperature.
