SN74LVC14APWRG3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SN74LVC14APWRG3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

The SN54LVC14A hex Schmitt-trigger inverter is

designed for 2.7-V to 3.6-V VCC operation, and the

SN74LVC14A hex Schmitt-trigger inverter is designed

for 1.65-V to 3.6-V VCC operation.

The devices contain six independent inverters and

perform the Boolean function Y = A.

Inputs can be driven from either 3.3-V or 5-V

devices. This feature allows the use of these devices

as translators in a mixed 3.3-V or 5-V system

environment.
