7.0 Absolute Maximum Ratings
Note :
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.
2. Functional operation should be restricted to recommended operating condition.
3. Exposure to higher than recommended voltage for extended periods of time could affect device reliability.

for device drain to source voltages from 0.25V to 1.0V. For a given output, it represents the maximum difference between pullup and pulldown drivers
due to process variation. The full variation in the ratio of the maximum to minimum pullup and pulldown current will not exceed 1.7 for device drain to
source voltages from 0.1 to 1.0.
