DESCRIPTION
The 74V1T14 is an advanced high-speed CMOS
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 noise
immunity and stable output.
Power down protection is provided on input and 0
to 7V can be accepted on input 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 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.
