Notes:
1. This 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. This excludes XTAL pins.
4. Device pin is not at an output Low state.

Stresses greater than those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This rating is a stress rating only. Functional operation of
the device at any condition above those indicated in the op-
erational sections of these specifications is not implied. Ex-
Total Power Dissipation =
posure to absolute maximum rating conditions for an ex-
tended period may affect device reliability.
Total power dissipation should not exceed 1.21 W for the
package. Power dissipation is calculated as follows:
