(1) All room temperature limits are 100% tested during production with TA = TJ = 25°C. All limits at temperature extremes are specified through correlation using standard Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
(2) Typical values are determined with TA = TJ = 25°C and represent the most likely norm.
