ELECTRICAL CHARACTERISTICS
(V
otherwise noted.) (Note 1)
Note 1: All devices are 100% production tested at T
Note 2: Too small to be measured in an ATE test environment. Only gross test to catch failures is implemented.
Note 3: Overdrive is defined as the voltage above or below the switching points.
Note 4: Guaranteed by ATE and/or bench characterization over temperature. V
Note 5: Hysteresis is half the input voltage difference between the two switching points.
Note 6: Includes reference error along with comparator offset voltage error.
