74VHC14 Datasheet PDF - ST Microelectronics

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.)
