Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.

Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25°C.
