(1)

All room temperature limits are 100% production tested. All limits at temperature extremes are specified through correlation using

standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

IQ specifies the current into the VIN pin and applies to non-switching operation.
