74LCX08TTR屬于集成電路（IC）的門反相器。由意法半導(dǎo)體集團制造生產(chǎn)的74LCX08TTR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。

描述 Description

The 74LCX08 is a low voltage CMOS QUAD 2-input AND gate fabricatedwith sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for inputs.
