cause permanent damage to the device.
Exposure to conditions beyond those indicated in the recommended
operational conditions of this specification may affect device reliability.
This is a stress rating only and functional operation of the device under
those conditions or at any other condition beyond those indicated in the
operational conditions of this specification is not implied.
It is not implied, that more than one of those conditions can be applied
simultaneously.
