74VHCT04A屬于集成電路（IC）的門反相器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的74VHCT04A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。

DESCRIPTION

The 74VHCT04A is an advanced high-speed CMOS HEX INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

The internal circuit is composed of 3 stages including buffer output, which provides high noise immunity and stable output.

■ HIGH SPEED: tPD = 4.7 ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION: ICC = 2 μA (MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS: VIH = 2V (MIN.), VIL = 0.8V (MAX)

■ POWER DOWN PROTECTION ON INPUTS & OUTPUTS

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ? tPHL

■ OPERATING VOLTAGE RANGE: VCC(OPR) = 4.5V to 5.5V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 04

■ IMPROVED LATCH-UP IMMUNITY

■ LOW NOISE: VOLP = 0.8V (MAX.)
