(1) Stresses beyond those listed under " absolute maximum ratings ” may cause permanent damage to the device. These are stress ratings
only, and 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.
