Notes:
1. Applies to all pins except XTAL pins and where otherwise noted.
2. There is no input protection diode from pin to V_DD and current into pin is limited to ±600 µA.
3. Excludes XTAL pins.
4. Device pin is not at an output Low state.

Stresses greater than those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This
rating is a stress rating only. Functional operation of the de-
vice at any condition above those indicated in the opera-
tional sections of these specifications is not implied. Expo-
sure to absolute maximum rating conditions for an extended
period may affect device reliability.
Total power dissipation should not exceed 1.21 W for the
package. Power dissipation is calculated as follows:
Total Power Dissipation = V_DD x [I_DD – (sum of I_OH),
+ sum of [(V_DD – V_OH) x I_OH]
+ sum of (V_OL x I_OL)
