Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is
used in this data sheet.
Note 3: -40°C specifications are guaranteed by design.

Note 6: Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured over
the specified analog signal ranges.
Note 7: Leakage parameters are 100% tested at hot temperature and guaranteed by correlation at room temperature.
Note 8: Guaranteed by design.
