DESCRIPTION

The 74VHCT132A is an advanced high-speed CMOS QUAD 2-INPUT SCHMITT NAND GATE fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

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 since all inputs are equipped with TTL threshold.

■ HIGH SPEED: tPD = 6.5 ns (TYP.) at VCC = 5V

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

■ TYPICAL HYSTERESIS : 0.7V at VCC = 4.5V

■ POWER DOWN PROTECTION ON INPUTS & OUTPUTS

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

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

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

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 132

■ IMPROVED LATCH-UP IMMUNITY

■ LOW NOISE: VOLP = 0.8V (MAX.)
