Normal Operating Conditions
Operating ranges define the limits for functional operation and parametric characteristics of the device as described in the
Normal Operating Conditions section and for the reliability specifications as listed in Detailed Hardware Description section.
Functionality outside these limits is not implied.
Total cumulative dwell time outside the normal power supply voltage range or the ambient temperature under bias, must be
less than 0.1% of the useful life as defined in Detailed Hardware Description section.
