3 Description

The SN74LV244A-Q1 octal buffers and line drivers

are designed for 2 V to 5.5 V VCC operation.

The device is configured into two banks of four

drivers, each controlled by its own output enable

pin. This device is fully specified for partial-powerdown

applications using Ioff. The Ioff circuitry disables

the outputs, preventing damaging current backflow

through the devices when they are powered down.
