74LCX574MTR集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

74LCX574MTR屬于集成電路（IC）的觸發(fā)器。由意法半導(dǎo)體集團制造生產(chǎn)的74LCX574MTR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

The 74LCX574 is a low voltage CMOS OCTAL D-TYPE FLIP FLOP with 3 STATE OUTPUT NON-INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs.
