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:

3. Peak Current. Do not exceed 25mA average current in either direction.
4. Excludes XTAL pins.
5. Device pin is not at an output Low state.
