Note 1:

Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device.

Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect device reliability.

Note 2:

formance specifications from 0°C to 85°C. Specifications over the –40°C

to 85°C operating temperature range are assured by design, characterization and correlation with statistical process

controls.
