DESCRIPTION

The 74VHC14 is an advanced high-speed CMOS HEX SCHMITT INVERTER 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 enables high noise immunity and stable output.

■ HIGH SPEED: tPD = 5.5ns (TYP.) at VCC = 5V

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

■ TYPICAL HYSTERESIS: Vh = 1V at VCC = 4.5V

■ POWER DOWN PROTECTION ON INPUTS

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

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ OPERATING VOLTAGE RANGE: VCC(OPR) = 2V to 5.5V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 14

■ IMPROVED LATCH-UP IMMUNITY

■ LOW NOISE: VOLP = 0.8V (MAX.)
