Minimum and Maximum limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through

correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

Typical numbers are at 25°C and represent the most likely parametric norm.
