February 1993 Revised April 2005

74LVX244 Low Voltage Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The LVX244 is an octal non-inverting buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver which provides improved PC board density. The inputs tolerate up to 7V allowing interface of 5V systems to 3V systems.

Features
s Input voltage translation from 5V to 3V s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise level and dynamic threshold performance
