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.
Note 4:

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 at
the extremes of the specified analog signal range.
Note 5:
Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
