(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.

(1) The JEDEC Low-K (1s) board design used to derive this data was a 3-inch x 3-inch, two-layer board with 2-ounce copper traces on top of
the board.
(2) The JEDEC High-K (2s2p) board design used to derive this data was a 3-inch x 3-inch, multilayer board with 1-ounce internal power and
ground planes and 2-ounce copper traces on the top and bottom of the board.
