Absolute maximum ratings are stress ratings only and operation at these maximums is not guaranteed. Stress beyond the limits
specified can affect device reliability or cause permanent damage to the device. For functional operating conditions, refer to the
remaining tables in this section.
This device contains circuitry to protect against damage due to high static voltage or electrical fields. It is advised, however, that
normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for instance, either V
or V
