SN74AC573DWR集成電路（IC）的鎖存器規(guī)格書PDF中文資料

SN74AC573DWR屬于集成電路（IC）的鎖存器。由德州儀器制造生產(chǎn)的SN74AC573DWR鎖存器鎖存器是類似于觸發(fā)器的基本數(shù)字存儲設備，但是不同之處在于，在鎖存使能（或類似命名）信號處于有效邏輯狀態(tài)的任何時間，保持的邏輯狀態(tài)都可以改變?！巴该鳌辨i存器還允許設備輸出在鎖存使能信號有效時反映輸入的當前狀態(tài)，而相反的是，狀態(tài)僅在保持狀態(tài)已固定時改變。

1 Features

? Operation of 2 V to 6 V V CC

? Inputs accept voltages to 6 V

? Maximum tpd of 9 ns at 5 V

? 3-State outputs drive bus lines directly

2 Applications

? Buffer registers

? Bidirectional bus drivers

? Working registers

3 Description

These 8-bit latches feature 3-state outputs designed

specifically for driving highly capacitive or relatively

low-impedance loads. The devices are particularly

suitable for implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.
