The parts are 100% tested at +25°C only, and guaranteed by design over the specified temperature range.
The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive
value is a maximum.
Guaranteed by design.
ΔRON = RON(MAX) - RON(MIN).
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Guaranteed by design.
Between any two switches.
