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 specification 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 3. The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor

discharged directly into each pin.
