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: ΔR

Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges, i.e., V
NO
= 3V to 0 and 0 to -3V.
Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation = 20log V
COM

COM
= output,
V
NO
= input to off switch.
Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
