Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using the

Statistical Quality Control (SQC) method.

(3)

Typical values represent the most likely parametric norm 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 ensured on shipped production

material.
