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

Ordering Code:

Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

Pb-Free package per JEDEC J-STD-020B.
