(2) 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. (3) Datasheet min/max specification limits are ensured by design, test, or statistical analysis. (4) Typical values represent most likely parametric norms at TA = 25 ºC, and at the Recommended Operation Conditions at the time of product characterization and are not ensured.
