1. When the input voltage at any pin exceeds the power supplies (that is VIN < AGND or VIN > AVCC or DVCC), the current at

that pin should be limited to 10 mA. A limit of 2 pins can sustain such a condition, limiting the current to 20 mA for the whole

device.

Note:

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the devices.

These are stress ratings only, which do not imply functional operation of the device at these or any other

conditions beyond those indicated under Recommended Operating conditions. Exposure to the absolute

maximum rating for extended periods may affect device reliability.
