DESCRIPTION
The 74LCX244 is a low voltage CMOS OCTAL
BUS BUFFER (NON-INVERTED) 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 both inputs
and outputs.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
This device is designed to be used with 3 state
memory address drivers, etc.
All
inputs
and
outputs
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
