Device Characteristics
Table 9. Absolute Maximum Ratings
The absolute maximum ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause
permanent damage to the device. None of the performance specification contained in this document are guaranteed when
operating at these maximum ratings.

1. If OVDD ≤ 0.4V, it is required that VDD ≤ 0.4V. Supply excursions not meeting this criteria must be limited to less than 25ms duration
during each power up or power down event.
2. This value is not a specification of the operational temperature range, it is a stress rating only.
Table 10. Recommended DC Operating Conditions (Sheet 1 of 2)
Device operation beyond the conditions specified is not recommended. Extended operation beyond the recommended
conditions can affect device reliability.
