SN74LV273APWR集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

SN74LV273APWR屬于集成電路（IC）的觸發(fā)器。由德州儀器制造生產(chǎn)的SN74LV273APWR觸發(fā)器觸發(fā)器是能夠存儲(chǔ)單個(gè)邏輯狀態(tài)或信息“位”的基本數(shù)字存儲(chǔ)器件。這些器件至少有兩個(gè)輸入；一個(gè)或多個(gè)用于傳遞要存儲(chǔ)的數(shù)據(jù)，另一個(gè)用于指示存儲(chǔ)該數(shù)據(jù)的時(shí)間點(diǎn)。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對(duì)提供給其輸入的信號(hào)有不同的響應(yīng)，可用于實(shí)現(xiàn)不同的邏輯功能。這些器件與鎖存器的不同之處在于它們是邊緣敏感器件，其保持的邏輯狀態(tài)僅在接收到有效時(shí)鐘信號(hào)時(shí)才會(huì)改變。
