HCPL3700S隔离器的光隔离器-晶体管光电输出规格书PDF中文资料

HCPL3700S属于隔离器的光隔离器-晶体管光电输出。由安森美半导体制造生产的HCPL3700S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。

描述 Description

The HCPL-3700 voltage/current threshold detection optocoupler consists of an AlGaAs LED connected to a threshold sensing input buffer IC which are optically coupled to a high gain darlington output. The input buffer chip is capable of controlling threshold levels over a wide range of input voltages with a single resistor. The output is TTL and CMOS compatible.
