DESCRIPTION
The 74LX1GU04 is a low voltage CMOS SINGLE
INVERTER (SINGLE STAGE) 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.
Power down protection is provided on input and
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.
All
inputs
and
outputs
are
equipped
with
protection circuits against static discharge.
