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 3: Guaranteed by design.

(min). On-resistance match between channels and flatness are guaranteed only with
specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as
measured over the specified analog signal range.
Note 5: Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temperature.
