(1)

Min and Max 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 TI's Average Outgoing Quality Level (AOQL).

(2)

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

(3)

Applies for packages soldered directly onto a 3” x 3” PC board with 2oz. copper on 4 layers in still air.
