(1) The Electrical Characteristics table lists specify 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
guaranteed.
(2) Datasheet min/max specification limits are specified by test, unless otherwise noted.
(3) Typical values represent the most likely parameter norms at T
A
= 25°C and at the Recommended Operation Conditions at the time of
product characterization and are not guaranteed.
