PARAMETER
The algebraic convention where the most negative value is a minimum and the most positive value a maximum is used in
this data sheet.
Guaranteed by design.
∆R
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25°C.
Off Isolation = 20 log
Between any two switches.
