４６５．Ｉ￣２Ｃ接点８位Ｉ／０芯片型ＰＣＦ８５７４应用很广泛，它可以和其它元件一起，应用于ＡＤ－ＤＡＩ／模块中，也可用于光继电器卡和ＬＣ显示中。由于经常需要将多个８５７４模块与Ｉ￣２Ｃ总线相连，故通过输入Ａ０－Ａ２给每个ＩＣ提供不同的地址是可能的。由...
465. I ~ 2C contact 8-bit I / O chip type PCF8574 is widely used, it can be used with other components, AD-DAI / module can also be used for light relay card and LC display. Since it is often necessary to connect multiple 8574 modules to the I2C bus, it is possible to provide each IC with a different address by entering A0-A2. by...
