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.)

74VHCT00属于集成电路（IC） > 门和反相器。意法半导体（ST）集团制造生产的74VHCT00门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。
