8. Min/Max limits are guaranteed by design, test or statistical analysis.
9. This parameter is not tested in production for 9Pin FlipChip CSP package in case of a 5.0 V power supply, however it is correlated based
on a 3.0 V power supply testing.
10.See page 11 for a theoretical approach of these parameters.
