DESCRIPTION

The 74LVX244 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 low

power, battery operated and low noise 3.3V

applications.

74LVX244TTR

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.
