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.)
