(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. No ensurance of 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 ensured 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 ensured on shipped
production material.
