DESCRIPTION
The 74LX1G04 is a low voltage CMOS SINGLE
INVERTER fabricated with sub-mi cron silic on
gate and double-layer metal wiring C
2
MOS
tecnology.
It is ideal for 1.65 to 5.5 V
CC
operations and low
power and low noise a pplications. The i nterna l
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 c an be accepted
on input with no regard to the supply voltage. T his
device can be used to interface 5V to 3V or lower
power supply system. The sub-m icron CMOS
technology used allow low power consumption
and guarantee optimized operation bet ween 2.8V
and 1.8V system, as Smart P hone, Digital Still
Camera, PDA, Notebook, or each battery
powered equipment.
All input and outputs are equipped with protection
circuits against ESD discharge.
