NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUMRATINGS may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied. Exposure
to absolute maximumrating conditions for extended periods may affect
reliability.
2. V

NOTE:
1. Tested at characterization and retested after any design or process change that
may affect these parameters.
