74ALVCH16374屬于集成電路（IC）的觸發(fā)器。由安森美半導體公司制造生產(chǎn)的74ALVCH16374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。

The 74ALVCH16374 is an advanced performance, non?inverting 16?bit D?type flip?flop. It is designed for very high?speed, very low?power operation in 1.8 V, 2.5 V or 3.3 V systems. The VCXH16374 is byte controlled, with each byte functioning identically, but independently. Each byte has separate Output Enable and Clock Pulse inputs. These control pins can be tied together for full 16?bit operation.
