M74HC14B1R集成電路（IC）的門反相器規(guī)格書PDF中文資料

M74HC14B1R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M74HC14B1R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(yīng)。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 M54/74HC14 is a high speed CMOS HEX SCHMITT INVERTER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. Pin configuration and function are the same as those of the HC04 but all inputs have 20 VCC hysteresis level.

This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED tPD = 11 ns (TYP.) AT VCC = 5 V

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

■ HIGH NOISE IMMUNITY VH = 1.1 V (TYP.) AT VCC = 5 V

■ OUTPUT DRIVE CAPABILITY 10 LSTTL LOADS

■ SYMMETRICAL OUTPUT IMPEDANCE ?IOH? = IOL = 4 mA (MIN.)

■ BALANCED PROPAGATION DELAYS tPLH = tPHL

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

■ PIN AND FUNCTION COMPATIBLE WITH 54/74LS14
