RELIABILITY CHARACTERISTICS
Data Retention…………………………..…..100 Years
Endurance…………………….……….100,000 Cycles
Note: The device is not guaranteed to function outside its
operating rating. Stresses listed under Absolute Maximum
Ratings may cause permanent damage to the device. These
are stress ratings only and functional operation of the device
at these or any other conditions outside those listed in the
operational sections of the specification is not implied.
Exposure to any absolute maximum rating for extended
periods may affect device performance and reliability.
Devices are ESD sensitive. Handling precautions are
recommended.
