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 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
).
