6N138S中文资料Low Input Current High Gain Split Darlington Optocouplers数据手册ONSEMI规格书

描述 Description

The 6N138/9 and HCPL2730/HCPL2731 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, HCPL2730/HCPL2731, 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.

简介

6N138S属于隔离器的光隔离器-晶体管光电输出。由制造生产的6N138S光隔离器 - 晶体管，光电输出晶体管或光电输出光隔离器通常出于安全或功能性原因，使用光来跨过电绝缘层进行信息传输。与其他光隔离器类型的区别在于，它们使用简单的光电晶体管或光伏电池（太阳能电池）作为输出设备。这些器件的输出不需要外部电源即可运行，并且具有模拟特性，因此可用于在无法实现电连接的电路之间传输模拟信息。
