DESCRIPTION

The M54/74HC03 is a high speed CMOS QUAD 2-INPUTOPEN DRAIN NANDGATE 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 buffer output, which gives high noise immunity and stable output. This device can, with an external pull-up resistor, be used in wired AND configuration.

This device can be also used as a led driver and in any other application requiring a current sink. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED tPZ = 5 ns (TYP.) AT VCC = 5 V

■ LOW POWER DISSIPATION ICC = 1 μA (MAX.) AT TA = 25 °C

■ HIGH NOISE IMMUNITY VNIH = VNIL = 28 VCC (MIN.)

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

■ WIDE OPERATING VOLTAGE RANGE VCC (OPR) = 2 V TO 6 V

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS03

M74HC03B1R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M74HC03B1R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。
