SN74LVC2G80DCTR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SN74LVC2G80DCTR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

This dual positive-edge-triggered D-type flip-flop is

designed for 1.65-V to 5.5-V VCC operation.

When data at the data (D) input meets the setup time

requirement, the data is transferred to the Q output on the positive-going edge of the clock pulse. Clock

triggering occurs at a voltage level and is not directly

related to the rise time of the clock pulse. Following

the hold-time interval, data at the D input can be

changed without affecting the levels at the outputs.

NanoFree? package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow through the device when it is powered down.
