23.2 Absolute Maximum Ratings

Maximum ratings are the extreme limits to which the MCU can be

exposed without permanently damaging it.

NOTE:

This device is not guaranteed to operate properly beyond the maximum

ratings. Refer to 5.0 V DC Electrical Characteristics for guaranteed

operating conditions.

NOTE:

This device contains circuitry to protect the inputs against damage due

to high static voltages or electric fields; however, it is advised that normal

precautions be taken to avoid application of any voltage higher than

maximum-rated voltages to this high-impedance circuit. For proper

operation, it is recommended that VIn and VOut be constrained to the

range VSS ≤ (VIn or VOut) ≤ VDD. Reliability of operation is enhanced if

unused inputs are connected to an appropriate logic voltage level (for

example, either VSS or VDD).
