“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

RatingsRatings 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. All voltages are measured with respect to the ground pin, unless otherwise specified

(2)

The Electrical Characteristics tables list guaranteed 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.

(3)

Typical values represent most likely parametric norms at TA = +25ºC, and at the Recommended Operation Conditions at the time of

product characterization and are not guaranteed.

(4)

Datasheet min/max specification limits are guaranteed by test or statistical analysis.
