M74HC174TTR集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

M74HC174TTR屬于集成電路（IC）的觸發(fā)器。由意法半導體集團制造生產的M74HC174TTR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，另一個用于指示存儲該數(shù)據的時間點。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。

DESCRIPTION

The M54/74HC174 is a high speed CMOS HEX DTYPE FLIP-FLOP WITH CLEAR fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.
