MC74HCT373A屬于集成電路（IC）的鎖存器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74HCT373A鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲(chǔ)設(shè)備，但是不同之處在于，在鎖存使能（或類似命名）信號(hào)處于有效邏輯狀態(tài)的任何時(shí)間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設(shè)備輸出在鎖存使能信號(hào)有效時(shí)反映輸入的當(dāng)前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時(shí)改變。

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.
