SPECIFICATIONS
V
IN
= 3.6 V, unless otherwise noted. Minimum and maximum values are guaranteed for T
J
= −40°C to +125°C. Typical values specified
are at T
J
= 25°C. All limits at temperature extremes are guaranteed by correlation and characterization using standard statistical quality
control (SQC), unless otherwise noted.
