MC74LCX374屬于集成電路（IC）的觸發(fā)器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74LCX374觸發(fā)器觸發(fā)器是能夠存儲單個邏輯狀態(tài)或信息“位”的基本數(shù)字存儲器件。這些器件至少有兩個輸入；一個或多個用于傳遞要存儲的數(shù)據(jù)，另一個用于指示存儲該數(shù)據(jù)的時間點。不同的觸發(fā)器類型，例如 D（延遲）、SR（置位復(fù)位）和 JK，對提供給其輸入的信號有不同的響應(yīng)，可用于實現(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)僅在接收到有效時鐘信號時才會改變。

Low-Voltage CMOS Octal D-Type Flip-Flop

With 5V–Tolerant Inputs and Outputs (3–State, Non–Inverting)

The MC74LCX374 is a high performance, non–inverting octal D–type flip–flop operating from a 2.3 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX374 inputs to be safely driven from 5V devices.
