Description
The 74LCXU04 is a low voltage CMOS HEX
inverter (single state) fabricated with sub-micron
silicon gate and double-layer metal wiring C

MOS
technology. It is ideal for low power and high
speed 3.3V applications. It can be interfaced to
5V signal environment for inputs.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

Maximum rating
stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. these are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. exposure to absolute maximum rating conditions for
extended periods may affect device reliability. refer also to the STMicroelectronics sure
program and other relevant quality documents.
