Absolute Maximum Ratings

Pin Configurations

Stresses beyond those listed under ‘‘Absolute Maximum Ratings’’ may cause

permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated

in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Also limited by package power dissipation limit, whichever is lower.
