SN74HC273QDWRG4Q1屬于集成電路（IC）的觸發(fā)器。由美國德州儀器公司制造生產(chǎn)的SN74HC273QDWRG4Q1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。

description/ordering information

This circuit is a positive-edge-triggered D-type

flip-flop with a direct clear (CLR) input.

Information at the data (D) inputs meeting the setup

time requirements is transferred to the Q outputs on

the positive-going edge of the clock (CLK) pulse.

Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the

positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
