Note 1: A typical is the center of characterization data taken with TA = TJ = 25°C. Typicals are not guaranteed.
Note 2: All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during
production with TA = TJ = 25°C. All hot and cold limits are guaranteed by correlating the electrical characteristics to
process and temperature variations and applying statistical process control.
