74VHCT00A集成電路（IC）的門反相器規(guī)格書PDF中文資料

74VHCT00A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74VHCT00A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 74VHCT00A is an advanced high-speed CMOS QUAD 2-INPUT NAND GATE 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 provide high noise immunity and stable output. Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V.

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

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

■ COMPATIBLEWITH TTL OUTPUTS: VIH = 2V (MIN), VIL = 0.8V(MAX)

■ POWERDOWN PROTECTIONON INPUTS & OUTPUTS

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

■ BALANCEDPROPAGATIONDELAYS: tPLH ? tPHL

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

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 00

■ IMPROVED LATCH-UP IMMUNITY

■ LOW NOISE: VOLP = 0.8V(Max.)
