Section 10. Electrical Characteristics
10.1  Introduction
This section contains electrical specifications for the M68HC11 E-series devices.
10.2  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 
10.5 DC Electrical Characteristics
, 
10.6 Supply Currents and Power 
Dissipation
, 
10.7 MC68L11E9/E20 DC Electrical Characteristics
, and 
10.8 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

 or V

) 
≤
 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
).
