(1) All limits are ensured by testing or statistical analysis.
(2) Typical values represent the most likely parametric norm.
(3) Slew rate is the average of the rising and falling slew rates.
(4) Offset voltage average drift determined by dividing the change in V_OS at temperature extremes by the total temperature change.
(5) Positive current corresponds to current flowing into the device.
