Note 2: All units are 100% production tested at T
A
= +85°C. Limits over the operating temperature range are guaranteed by design
and characterization and are not production tested.
Note 3:

.
Note 4: Guaranteed by design. Not production tested.
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.
