DESCRIPTION

The 74V1T14 is an advanc ed high-speed CM OS
SINGLE 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 provide high no ise
immunity and stable output.
Power down protection is provided on inpu t an d 0
to 7V can be acce pted on inp ut with no rega rd to
the supply voltage. This device can be used to

interface 5V to 3V . Pin conf iguration and function
are the same as those of the 74V1T04 but the
74V1T14 has hysteresis.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fall input signals.
The input is equipped with protection circuits
against static discharge, giving it ESD immunity
and transient excess voltage.
