M74HC377集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

M74HC377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M74HC377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據，另一個用于指示存儲該數據的時間點。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 M74HC377 is an high speed CMOS OCTAL D TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the positive going edge of the clock pulse if the enable input Gis low. Clock triggering occurs at a particular voltage level and is not directly relatedto the transition time of the positive going pulse. When the clock input is at either the high or low level, the D input signal has no effect at the output. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
