Note 2: All devices are 100% production tested at TA = +25NC. Temperature limits are guaranteed by design.
Note 3: Hysteresis is the input voltage difference between the two switching points.
Note 4: VOS is the average of the positive and negative trip points minus VREF.
Note 5: Overdrive is defined as the voltage above or below the switching points.
