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: ∆R

= R
ON(MAX)
- R
ON(MIN)
.
Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at T
A
= +25°C.
Note 7: If the logic inputs can float during power-on, connect a 1MΩ pull-up from LATCH to V+; see

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