74LVCH32373A是32位D型穿透锁存器,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态输出。每个八位部分都提供一个锁存使能(nLE)输入和一个输出使能输入(nOE)。输入可通过3.3 V或5 V器件进行驱动。
该器件由八个带3态真正输出的D型穿透锁存器的4部分组成。输入nLE为高电平时,nDn输入处的数据会输入锁存器。在这种情况下,锁存器是穿透的,即每当与锁存输出对应的D输入发生变化时,锁存输出都会随之变化。
输入nLE为低电平时,锁存器存储nLE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。输入nOE为低电平时,八个锁存器的内容可在输出上获取。输入nOE为高电平时,输出转为高阻抗关断状态。nOE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。在3态操作中,输出能处理5 V的电压。这些特性允许在混合3.3 V和5 V环境中使用这些器件。
数据输入上的总线保持无需使用外部上拉电阻来保持未使用的输入。
