SN74AC573集成電路（IC）的鎖存器規(guī)格書(shū)PDF中文資料

SN74AC573屬于集成電路（IC）的鎖存器。由德州儀器制造生產(chǎn)的SN74AC573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。
