74AHC(T)157: 四路2输入多路复用器
74AHC/AHCT157是高速硅栅CMOS器件，与低功耗肖特基TTL (LSTTL)针脚兼容。其规格符合JEDEC标准no. 7A。
74AHC/AHCT157是四路2输入多路复用器，其在公共数据选择输入的控制下从两个数据源选择4位数据。使能输入(E)为低电平有效。E为高电平时，无论所有其他输入条件如何，所有输出（1Y至4Y）都被强制为低电平。
将数据从两组寄存器移动到四个公共输出总线是74AHC/AHCT157的常见用途。公共数据选择输入(S)的状态可确定数据来自哪个特定的寄存器。其还可以用作函数生成器。该器件在实施极不规则的逻辑时非常有用，方法是生成两个变量（其中一个变量为通用变量）的16个不同函数中的任意四个，74AHC/AHCT157是4极2位置开关的逻辑实施，其中开关位置由施加到S的逻辑电平确定。
逻辑方程式为：
74AHC/AHCT157等同于74AHC/AHCT158，但具有非反相（真正）输出。
