74LV138: 3至8线路解码器/解复用器;反相

74LV138是低压硅栅CMOS器件,与74HC138和74HCT138针脚和功能兼容。

74LV138是3至8线路解码器/解复用器。其接受三个二进制加权地址输入(A0、A1和A2),处于使能状态时提供八个互斥低电平有效输出(U0至Y7)。

有三个使能输入:两个低电平有效(E1和E2)和一个高电平有效(E3)。除非E1和E2为低电平且E3为高电平,否则每个输出都将是高电平。

该多路使能功能只需凭借四个74LV138器件和一个反相器, 即能将该器件轻松并行扩展为32选1(5线路至32线路)解码器。通过将某个低电平有效使能输入用作数据输入以及将剩下的使能输入用作选通,74LV138可用作一个八输出解复用器。未使用的使能输入必须恒定地连接到其相应的高电平或低电平有效状态。
