DESCRIPTION
The 74LCX05 is a low voltage CMOS OPEN
DRAIN HEX INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low power
and high speed 3.3V applications. It can be
interfaced to 5V signal environment for inputs.
The internal circuit is composed of 3 stages
including buffer output, which provides high noise
immunity and stable output.
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.
