Note 2:
Absolute Maximum Rating indicate limits beyond which damage to the device may occur.
Note 3:
Operating Ratings indicate conditions for which the device is 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. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
Note 4:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 5:
Typical specifications are specified at +25C and represent the most likely parametric norm.
Note 6:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
