(2) Typical values represent most likely parametric norms at specific conditions (Example Vcc; specific temperature) and at the
recommended Operating Conditions at the time of product characterizations and are not ensured.
(3) The Electrical characteristics tables list ensured specifications under the listed Operating Ratings except as otherwise modified or
specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not ensured.
