MC74HCT373ADWG集成电路（IC）的锁存器规格书PDF中文资料

MC74HCT373ADWG属于集成电路（IC）的锁存器。由安森美半导体制造生产的MC74HCT373ADWG锁存器锁存器是类似于触发器的基本数字存储设备，但是不同之处在于，在锁存使能（或类似命名）信号处于有效逻辑状态的任何时间，保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态，而相反的是，状态仅在保持状态已固定时改变。

Octal 3-State Noninverting Transparent Latch with LSTTL-Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT373A may be used as a level converter for interfacing TTL or NMOS outputs to High−Speed CMOS inputs.

The HCT373A is identical in pinout to the LS373.

The eight latches of the HCT373A are transparent D−type latches.

While the Latch Enable is high the Q outputs follow the Data Inputs.

When Latch Enable is taken low, data meeting the setup and hold times becomes latched.
