74HC(T)4514: 4至16线路解码器/解复用器，具有输入锁存器
74HC/1是高速硅栅CMOS器件，与“4000B”系列的“4514”针脚兼容。其规格符合JEDEC标准no. 7A。
74HC/HCT4514是带锁存器的4至16线路解码器/解复用器，具有四个二进制加权地址输入（A0至A3）、一个锁存使能输入(LE)以及一个低电平有效使能输入(E)。16个输出（Q0至Q15）为互斥高电平有效。LE为高电平时，所选输出由An上的数据确定。LE变为低电平时，最后出现在An上的数据存储在锁存器中且输出保持稳定。E为低电平时，由锁存器中的内容确定的所选输出为高电平。E为高电平时，所有输出都为低电平。使能输入(E)不影响锁存器的状态。
“4514”用作解复用器时，E是数据输入，A0至A3是地址输入。
