(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. No specified parametric performance is
indicated in the electrical tables under conditions different than those tested
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control (SQC) methods.
(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.
