378 Freescale Semiconductor
23.2 Introduction
This section contains electrical and timing specifications. These values
are design targets and have not yet been fully tested.
23.3 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 23.6 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
).
