M74HCT04B1屬于集成電路（IC）的門反相器。由意法半導體集團制造生產(chǎn)的M74HCT04B1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。雖然早就被集成電路實施形式所取代，以用于實現(xiàn)復雜功能，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

The M54/74HCT04 is a high speed CMOS INVERTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

The internal circuit is composed of 3 stages including buffered output, which gives high noise immunity and a stable output.

All inputs are equipped with protection circuits against static discharge or transient excess voltage. This integrated circuit has input and output characteristic that are fully compatible with 54/74 LSTTL logic families. M54HCT/74HCT devices are designed to directly interface HSC2MOS systems with TTL and NMOS components. They are also plug in replacements for LSTTL devices giving a reduction of power consumption.
