Notes: 7. Shorting output to V+ will adversely affect reliability.
8. Shorting output to V- will adversely affect reliability.
9. Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time
and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production
material.
10. All limits are guaranteed by testing or statistical analysis.
