MC74VHCT573ADW集成電路（IC）的鎖存器規(guī)格書PDF中文資料

MC74VHCT573ADW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MC74VHCT573ADW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。

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.
