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. VDD).
