DESCRIPTION
The 74LCX07 is a low voltage CMOS OPEN
DRAIN HEX BUFFER fabricated with sub-micron
silicon gate and double-layer me tal wiring C
2
MOS
technology. It is ideal for low power and high
speed 3.3V applications. It canbeinterfaced to 5V
signal environment for inputs.
The internal circuit is composed of 2 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 stat ic discharge, giving
them 2K V ESD imm unit y and transient excess
voltage.
