(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions.
(2) The Electrical characteristics tables list specifications under the listed Recommended Conditions except as otherwise modified or
specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are NOT specified.
(3) Typical values represent most likely parametric norms at specific conditions (Example VA; specific temperature) and at the
recommended Operating Conditions at the time of product characterizations and are NOT specified.
