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