Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: Guaranteed by design.
Note 4: ∆R
Note 5: Resistance flatness is defined as the difference between the maximum and the minimum value of on-resistance as mea-
Note 6: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
Note 7: Off isolation = 20log
Note 8: Between any two switches.
Note 9: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
