SN74LVC2G00DCUTG4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SN74LVC2G00DCUTG4門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對(duì)單個(gè)邏輯信號(hào)執(zhí)行基本邏輯運(yùn)算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲(chǔ)信息，不會(huì)對(duì)提供給其輸入的信號(hào)立即做出響應(yīng)。雖然早就被集成電路實(shí)施形式所取代，以用于實(shí)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-NAND gate is designed for

1.65-V to 5.5-V VCC operation.

The SN74LVC2G00 device performs the Boolean

function Y = A × B or Y = A + B 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.
