= -40°C to +125°C, unless otherwise noted. Typical values
are at T A = +25°C and V CC = +5V, unless otherwise noted.) (Note 1)
Note 1: 100% production tested at T A = +25°C. Specifications over temperature limits are guaranteed by design.
Note 2: T

are factory-programmed temperature trip thresholds from -40°C to +125°C in 5°C increments.
Note 3: Temperature threshold hysteresis is defined as the difference from positive-going temperature thresholds minus the nega-
tive-going temperature thresholds.
