SN74LVC74APWRE4集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

SN74LVC74APWRE4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SN74LVC74APWRE4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，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。

3 Description

The SNx4LVC74A devices integrate two positive-edge

triggered D-type flip-flops in one convenient device.

The SN54LVC74A is designed for 2.7V to 3.6V VCC

operation, and the SN74LVC74A is designed for

1.65V to 3.6V VCC operation.
