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-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
