描述 Description

The MC74LVX74 is an advanced high speed CMOS D-type flip-flop. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems. The signal level applied to the D input is transferred to O output during the positive going transition of the Clock pulse. Clear (CD) and Set (SD) are independent of the Clock (CP) and are accomplished by setting the appropriate input Low.

簡(jiǎn)介

MC74LVX74屬于集成電路（IC）的觸發(fā)器。由制造生產(chǎn)的MC74LVX74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。
