Test circuit in Figure 22 and Figure 27.

(2)

All limits specified at room temperature TYP and MAX. 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.

6.7 Electrical Characteristics – 5-V Version
