3 Description

The SN74LV244A octal buffers and line drivers are

designed for 2-V to 5.5-V VCC operation.

The SN74LV244A devices are designed specifically

to improve both performance and density of the 3-

state memory address drivers, clock drivers, and busoriented

receivers and transmitters. These devices

are organized as two 4-bit line drivers with separate

output-enable (OE) inputs.
