Min and Max limits are 100% production tested at 25 ºC. Limits over the operating temperature range are guaranteed through
correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level
(AOQL).
(2)
Device thermal limitations may limit usable range.
