Note 3: UCSP parts are 100% tested at +25°C only, and guaranteed by design over the specified temperature range. µMAX parts
are 100% tested at T
MAX
and guaranteed by design over the specified temperature range.
Note 4: 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.
Note 5: Guaranteed by design for UCSP parts.

Note 7: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 8: Guaranteed by design.
