(1) All limits are ensured by testing or statistical analysis.
(2) Typical values represent the most likely parametric norm.
(3) Slew rate is the "worst case" of the rising and falling slew rates.
(4) Output Swing not limited by Slew Rate limit.
(5) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
