MC74VHC1G02屬于集成電路（IC）的門反相器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC74VHC1G02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(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。

The MC74VHC1G02 / MC74VHC1GT02 is a an advanced high

speed CMOS 2?input NOR gate in tiny footprint packages. The

MC74VHC1G02 has CMOS?level input thresholds while the

MC74VHC1GT02 has TTL level thresholds.

The input structures provide protection when voltages up to 5.5 V

are applied, regardless of the supply voltage. This allows the device to

be used to interface 5 V circuits to 3 V circuits. Some output structures

also provide protection when VCC = 0 V and when the output voltage

exceeds VCC. These input and output structures help prevent device

destruction caused by supply voltage ? input/output voltage mismatch,

battery backup, hot insertion, etc.
