DESCRIPTION
The 74LVC244A is a low voltage CMOS OCTAL
BUS BUFFER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C²MOS technology. It is ideal for 1.65 to 3.6
V_CC operations and low power and low noise
applications.

It can be interfaced to 5V signal environment for
inputs in mixed 3.3/5V system.
G control output governs four BUS BUFFERs.
This device is designed to be used with 3 state
memory address drivers, etc.
It has more 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.
