MC74VHC1GT14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MC74VHC1GT14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。

Single Schmitt-Trigger Inverter

The MC74VHC1G14 / MC74VHC1GT14 is a single Schmitt?Trigger Inverter in tiny footprint packages. The MC74VHC1G14 has CMOS?level input thresholds while the MC74VHC1GT14 has TTL?level input thresholds.

The internal circuit is composed of three stages, including a buffered output which provides high noise immunity and stable output.

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. The 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.
