QX4506 包含一个GaAsPLED，它被光学耦合到一个集成的高增益光电探测器。 芯片上的20KΩ输出上拉电阻可以通过短接输出引脚6和7来启用，因此在常见的IPM应用中不需要外部上拉电 阻。 The QX4506 contain a GaAsP LED, it is optically coupled to an integrated high gain photo detector. An on chip 20 KΩ output pull-up resistor can be enabled by shorting output pins 6 and 7, thus eliminating the need for an external pull-up resistor in common IPM applications.
