Exceeding any one or a combination of the Absolute
Maximum Rating conditions may cause permanent
damage to the device. Extended application of Absolute
Maximum Rating conditions to the device may reduce
device reliability. Specified typical performance or
functional operation of the device under Absolute
Maximum Rating conditions is not implied.

* MTTF – Median time to failure as determined by the process technology wear-out failure mode. Refer to product qualification report for FIT
(random) failure rate.
Operation of this device beyond any one of these limits may cause permanent damage. For reliable continuous operation, the device voltage and
current must not exceed the maximum operating values specified in the table above.
