Stresses beyond those

listed under “absolute maximum ratings” may cause permanent damage to the device. These are

stress ratings only, functional operation of the device at these or any other conditions beyond those indicated under

“recommended operating conditions” is not implied. Exposure to absolute maximum-rated conditions for extended

periods may affect device reliability.
