Description
The 74LCX02 is a low voltage CMOS quad 2-
input NOR gate fabricated with sub-micron silicon
gate and double-layer metal wiring C2MOS
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.
