Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

(2)

All limits are ensured by test or statistical analysis.

(3)

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 specified on shipped

production material.

(4)

All limits are ensured by design and measurements which are performed on a limited number of samples. Limits represent the mean

±3–sigma values. The typical value represents the statistical mean value.
