Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions,
see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.

Note 4: Guaranteed and 100% production tested.
Note 5: Guaranteed, but not 100% production tested. These limits are not used to calculate average outgoing quality levels.
Note 6: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between
the operating TMAX and TMIN, divided by TMAX-TMIN. The measured temperatures are -55
oC, -40oC, 0oC, 25oC, 70oC, 85oC, 125oC.
