17.3 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 at the maximum
ratings. Refer to

17.6 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 V

IN

and V

OUT

be constrained to the

range V

SS

≤

(V

IN

or V

OUT

)

≤

V

DD

. Reliability of operation is enhanced if

unused inputs are connected to an appropriate logic voltage level (for
example, either V

SS

or V

DD

.)
