逻辑电路:异或(XOR)电路

异或电路
异或电路

通过结合以上所述基本逻辑电路,可以配置具有特定功能的电路。

此处,我们将说明用于比较器的异或(XOR)(*)电路,该比较器用于检查数据不匹配和加法器。

图中,开关按下的状态定义为打开,拉起的状态定义为关闭。

当开关A为“ ON”时,上电路接通,下电路断开。
反过来,当开关A为“ OFF”时,下电路接通,上电路断开。
当开关B为“ ON”时,上电路断开,下电路接通。
反过来,当开关B为“ OFF”时,下电路断开,上电路接通。

如图所示,如果将开关A、B组合在一起,则当A、B均为“ ON”或“ OFF”时,无电流流过,灯泡不亮。
只有当A、B不匹配时(例如A为“ ON”且B为“ OFF”),电路才会接通,灯泡才会亮。

如真值表所示,向A或B输入1时,输出Y都为1。
原理图可用MIL符号表示,如右图所示。
