Notes:

1. Applies to all pins except XTAL pins and where otherwise noted.

2. There is no input protection diode from pin to VDD 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 = VDD x [IDD – (sum of IOH),

+ sum of [(VDD – VOH) x IOH]

+ sum of (VOL x IOL)
