ELECTRICAL CHARACTERISTICS (continued)
(V
unless otherwise noted.) (Note 2)
Note 2: All devices are 100% production tested at T
Note 3: Hysteresis is the input voltage difference between the two switching points.
Note 4: V
Note 5: Overdrive is defined as the voltage above or below the switching points.
