Note: 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 above those indicated in the operational section of this
specification is not implied. Exposure to absolute maximum rating condition 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 the
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 (e.g., V
DD
).
