DESCRIPTION
The 74LVX244 is a low voltage CMOS OCTAL
BUS BUFFER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low
power, battery operated and low noise 3.3V
applications.
G
output enable governs four BUS BUFFERs
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage.
This device can be used to interface 5V to 3V. It
combines high speed performance with the true
CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
