(1) All limits are specified at TA = TJ = 25°C only (standard typeface) or over the entire operating temperature range of the indicated device
(boldface type). All limits at TA = TJ = 25°C are 100% production tested. All limits at temperature extremes are specified via correlation
using standard Statistical Quality Control methods.
(2) All limits are specified at TA = TJ = 25°C only (standard typeface) or over the entire operating temperature range of the indicated device
(boldface type). All limits are 100% production tested and are used to calculate Outgoing Quality Levels.
