Electrical Specifications
16.1 Introduction
This section contains electrical and timing specifications.
16.2 Absolute Maximum Ratings
Maximum ratings are the extreme limits to which the microcontroller unit (MCU) can be exposed without
permanently damaging it.
NOTE
This device is not guaranteed to operate properly at the maximum ratings.
Refer to
16.5 5-V DC Electrical Characteristics
and
16.6 3-V DC Electrical
Characteristics
for guaranteed operating conditions.
Table 16-1. Absolute Maximum Ratings
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
.)
