6 ELECTRICAL CHARACTERISTICS
6.1 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
Notes:
- Stresses above those listed as ”absolute maximum ratings” may cause permanent damage to the device. This is a stress rating only and
- (1) Within these limits , clamping diodes are guarantee to be not conductive. Voltages outside these limits are authorised as long as injection
functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended period s may
affect device reliability.
