SN74LVC2G08DCTRG4屬于集成電路（IC）的門反相器。由美國德州儀器公司制造生產(chǎn)的SN74LVC2G08DCTRG4門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對單個邏輯信號執(zhí)行基本邏輯運算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲信息，不會對提供給其輸入的信號立即做出響應(yīng)。雖然早就被集成電路實施形式所取代，以用于實現(xiàn)復(fù)雜功能，但分立柵極仍可在僅需要非常簡單邏輯功能的情況下使用。

3 Description

This dual 2-input positive-AND gate is designed for

1.65-V to 5.5-V VCC operation.

The SN74LVC2G08 device performs the Boolean

function in positive logic.

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.
