Notes:

4. The JEDEC high-K (2s2p) board used to derive this data was a 3 inch

 3 inch, multilayer board with 1oz internal power and ground planes with

2oz copper traces on top and bottom of the board.

5. Thermal resistance from junction to case.

Caution:

Stresses greater than the 'Absolute Maximum Ratings' specified above, can cause permanent damage to the device. These are stress ratings only;

functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability can be

affected by exposure to absolute maximum rating conditions for extended periods of time.
