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.
