74LVC573A：八进制D型透明锁存器，具有5 V容压输入/输出；3态

74LVC573A由八个D型透明锁存器组成，具有适用于每个锁存器的单独D型输入和适合总线应用的3态真正输出。锁存使能输入(LE)和输出使能输入(OE)为所有内部锁存器共用。

LE为高电平时，Dn输入处的数据会输入锁存器。在这种情况下，锁存器是透明的，即每当与锁存输出对应的D输入发生变化时，锁存输出就会随之变化。LE为低电平时，锁存器存储LE从高电平跃迁至低电平前的一个设置时间在D输入处出现的信息。

OE为低电平时，八个锁存器的内容可在输出上获取。OE为高电平时，输出转为高阻抗关断状态。OE输入的操作不会影响锁存器的状态。

输入可通过3.3 V或5 V器件进行驱动。禁用时，可以向输出施加高达5.5 V的电压。这些特性允许将这些器件用作混合3.3 V或5 V应用中的转换器。

74LVC573A在功能上等同于74LVC373A，但针脚排列不同。
