SN74S38集成電路（IC）的門反相器規(guī)格書PDF中文資料

SN74S38屬于集成電路（IC）的門反相器。由德州儀器制造生產(chǎn)的SN74S38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。

description

These devices contain four independent 2-input NAND

buffer gates with open-collector outputs. The open-

collector outputs require pull-up resistors to perform

correctly. They may be connected to other open-

collector outputs to implement active-low wired-OR or

active-high wired-AND functions. Open-collector

devices are often used to generate high VOH levels.

The SN5438, SN54LS38, and SN54S38 are

characterized for operation over the full military

temperature range of ~55°C to 125°C. The SN7438,

SN74LS38, and SN74S38 are characterized for opera-

tion from 0°C to 70°C.
