DESCRIPTION
The 74VHC14 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 enables high noise
immunity and stable output.
Power down protection is provided on all inputs
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 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.
