MC74VHCT573ADT集成電路（IC）的鎖存器規(guī)格書PDF中文資料

MC74VHCT573ADT屬于集成電路（IC）的鎖存器。由安森美半導體公司制造生產的MC74VHCT573ADT鎖存器鎖存器是類似于觸發(fā)器的基本數字存儲設備，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。

The MC74VHCT573A is an advanced high speed CMOS octal latch with 3?state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
