DESCRIPTION
The 74VHCT14A is an advanced high-speed
CMOS HEX SCHMITT INVERTER fabricated
with sub-micron silicon gate and double-layer
metal wiring C
2
MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which enable 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.
Pin configuration and function are the same as
those of the VHC04 but the VHC14 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.
