ABSOLUTE MAXIMUM RATINGS

Stresses greater than those listed under Absolute Maximum
Ratings can cause permanent damage to the device. This rat-
ing is a stress rating only. Functional operation of the device
at any condition above those indicated in the operational
sections of these specifications is not implied. Exposure to
absolute maximum rating conditions for an extended period

can affect device reliability. Total power dissipation should
not exceed 880 mW for the package. Power dissipation is
calculated as follows:
