. On-resistance match between channels and on-resistance 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 3:
Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temp.
Note 4:
Guaranteed by design.
Note 5:
Leakage testing at single supply is guaranteed by testing with dual supplies.
