SN74F174AD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SN74F174AD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

This monolithic, positive-edge-triggered flip-flop utilizes TTL circuitry to implement D-type flip-flop logic with a

direct clear (CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred

to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs at a particular voltage level

and is not directly related to the transition time of the positive-going pulse. When the clock (CLK) input is at either

the high or low level, the D-input signal has no effect at the output.

The SN74F174A is characterized for operation from 0°C to 70°C.
