Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. 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 2: This test is performed by shifting the input voltage in 50mV increments until output reaches 4.706V.

Note 5: Guaranteed parameter, not tested.

Note 6: Human body model, 1.5k
