Note 1:
Exceeding the absolute maximum rating may damage the device.
Note 2:
The device is not guaranteed to function outside its operating rating. The SE3506 is guaranteed to meet
specifications from 0°C to 70°C. Specifications over the –40°C to 85°C operating temperature range are assured by
design, characterization and correlation with statistical process controls.
