SN74AHCT02集成電路（IC）的門反相器規(guī)格書PDF中文資料

SN74AHCT02屬于集成電路（IC）的門反相器。由德州儀器制造生產(chǎn)的SN74AHCT02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

These devices contain four independent 2-input NOR

gates that perform the Boolean function Y = A· B or Y

= A + B in positive logic.
