NOTES:
1. Permanent damage can occur if maximum ratings are exceeded. Exposure
to voltages or currents in excess of recommended values affects device
reliability. Device modules may not operate normally while being exposed
to electrical extremes.
2. Although sections of the device contain circuitry to protectagainst damage
from high static voltages or electrical fields, take normal precautions to
avoid exposure to voltages higher than maximum-rated voltages.
This device contains protective
circuitry against damage due to
high static voltages or electrical
fields; however, it is advised 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 (e.g., either GND
or V _CC ).
The following ratings define a range of conditions in which the device will operate without
being damaged. However, sections of the device may not operate normally while being
exposed to the electrical extremes.
