noted.) (Note 3)

Note 3: All units are 100% production tested at T

= +85NC. Limits over the operating temperature range are guaranteed by

design and characterization and are not production tested.

Note 5: Guaranteed by design. Not production tested.
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal range.
