Description

The M54HCxxx and M54HCTxxx series are composed of over 90 types of high speed CMOS functions specifically designed to meet the radiation requirements of the aerospace industry. It includes a large set of gates, Flip-Flops, Multiplexers, Counters, Bus interface and several other functions. The radiation hardness, the single event latch-up (SEL) immunity and the housing in hermetic packages of all types of both series make them ideally suited for use in the most difficult environmental conditions.

■ The complete specification of each type is available from the ESCC web site: https://escies.org using its ESCC part number.

ST guarantees full compliance of qualified parts with these ESCC specifications

M74HC32屬于集成電路（IC） > 門和反相器。意法半導(dǎo)體（ST）集團(tuán)制造生產(chǎn)的M74HC32門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對單個(gè)邏輯信號執(zhí)行基本邏輯運(yùn)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(shí)施形式所取代，以用于實(shí)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。
