Note 3: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 4: Guaranteed by design.

.
Note 6: Resistance flatness is defined as the difference between the maximum and minimum on-resistance values, as measured
over the specified analog signal range.
Note 7: Leakage parameters are 100% tested at maximum rated temperature, and guaranteed by correlation at T
A
= +25°C.

Note 9: Between any two switches.
Note 10: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
