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

Quality Control (SQC) methods. The limits are used to calculate TI's Averaging Outgoing Quality Level (AOQL).

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