Low noise: VOLP = 0.8V (Max.)
Description
The 74VHCT14A 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 provides 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 since all
inputs are equipped with TTL threshold.
SO-14
TSSOP14
Pin configuration and function are the same as
those of the 74VHC04 but the 74VHC14 has
hysteresis.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fall input signals.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current
consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation.
ICC(opr) = CPD x VCC x fIN + ICC/6 (per gate)
