6. Absolute Maximum Ratings
Stresses greater than those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at any condition beyond those indicated in the operational section of these specification is not
implied. Exposure to absolute maximum rating conditions for an extended period may affect device reliability. All inputs and outputs are
protected against high electrostatic voltages or electric fields. However, precautions to minimize build-up of electrostatic charges during
handling are recommended. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (for
example, V_DD).
