Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits

and associated test conditions, see the Electrical Characteristics tables.

(2)

All voltages are with respect to the potential at the GND pin.

(3)

The part cannot dissipate more than 400mW.

(4)

The human-body model is 100 pF discharged through 1.5 k

Ω. The machine model is 0Ω in series with 100 pF.
