11.3 Maximum Ratings
Maximum ratings are the extreme limits to which the MCU can be
exposed without permanently damaging it.
The MCU contains circuitry to protect the inputs against damage from
high static voltages; however, do not apply voltages higher than those
shown in the table below. Keep V
IN
and V
OUT
within the range
V
SS
≤ (V
IN
or V
OUT
) ≤ V
DD
. Connect unused inputs to the appropriate
voltage level, either V
SS
or V
DD
.
NOTE: This device is not guaranteed to operate properly at the maximum
ratings. Refer to 11.6 DC Electrical Characteristics (5.0 Vdc) and 11.7
DC Electrical Characteristics (2.2 Vdc) for guaranteed operating
conditions.
