Stresses beyond 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 conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods can affect device reliability. b). Ratings apply to ambient temperature at +25C. The JEDEC High-K board design used to derive this data is a 2inch 2inch multi-layer board with 1oz internal power and ground planes and 2oz copper traces on the top and bottom of the board.
