7 ELECTRICAL CHARACTERISTICS
7.1 ABSOLUTE MAXIMUM RATINGS
This product contains devices to protect the inputs
against damage due to high static voltages, how-
ever it is advisable to take normal precaution to
avoid application of any voltage higher than the
specified maximum rated voltages.
For proper operation it is recommended that V
and V
Reliability is enhanced if unused inputs are con-
nected to an appropriate logic voltage level (V
or V
Note: Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is
