11.2 Introduction
This section contains electrical specifications for the M68HC11 E-series
devices.
11.3 Maximum Ratings for Standard and Extended Voltage Devices
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
11.6 DC Electrical Characteristics

11.8 MC68L11E9/E20 DC
Electrical Characteristics
, and
11.9 MC68L11E9/E20 Supply
Currents and Power Dissipation
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

)
≤

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
).
