(1) The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not ensured.
(2) Typical values represent most likely parametric norms at T
A
= +25ºC, and at the Recommended Operation Conditions at the time of
product characterization and are not ensured.
(3) Datasheet min/max specification limits are ensured by test or statistical analysis.
