Notes: 4. 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 conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods
may affect device reliability.
5. Ratings apply to ambient temperature at 25°C . The JEDEC High-K board design used to derive this data was a 2 inch x 2 inch multilayer board
with 1-ounce internal power and ground planes and 2-ounce copper traces on the top and bottom of the board.
