SN74LV1T32集成電路（IC）的門反相器規(guī)格書PDF中文資料

SN74LV1T32屬于集成電路（IC）的門反相器。由德州儀器制造生產(chǎn)的SN74LV1T32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 SN74LV1T32-Q1 is a 2-input OR Gate. Each

gate performs the Boolean function Y = A + B in

positive logic. The output level is referenced to the

supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V,

and 5V CMOS levels.

The input is designed with a lower threshold circuit to

support up translation for lower voltage CMOS inputs

(for example, 1.2V input to 1.8V output or 1.8V input

to 3.3V output). In addition, the 5V tolerant input pins

enable down translation (for example, 3.3V to 2.5V

output).
