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