Note:

4. a). Stresses greater than those listed under Absolute Maximum Ratings can 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 Ratings for extended periods can affect device reliability.

b). Ratings apply to ambient temperature at +25°C. The JEDEC High-K board design used to derive this data was a 2inch x 2inch multilayer board with

1oz internal power and ground planes and 2oz copper traces on the top and bottom of the board.
