DESCRIPTION
The 74LX1G14 is a low voltage CMOS SINGLE
SCHMITT INVERTER fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology.
It is ideal for 1.65 to 5.5 V
CC
operations and low
power and low noise applications. The internal
circuit is composed of 3 stages including buffer
output, which provide high noise immunity and
stable output.
Powerdownprotectionisprovidedoninputand
output and 0 to 7V can be accepted on inputs with
no regard to the supply voltage. It can be
interfaced to 5V signal environment for inputs in
mixed 3.3/5V system.
Pin configuration and function are the same as
those of the 74LX1G04 but the 74LX1G14 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.
