Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: Parts are tested at +85°C and guaranteed by design and correlation over the full temperature range.

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