6N138 系列 单通道 0.5 mA 2000% CTR 达林顿 光电耦合器 - 8 引脚
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.
