Note 1: All devices are 100% production tested at T
J
= +25°C and T
J
= +125°C. Limits to T
A
= -40°C are guaranteed by design.
Note 2: Guaranteed by design, not production tested.
Note 3: Parameter is measured at trip point of latch with V
FB
= 0V.
Note 4: Gain is defined as A = ∆V

Note 5: See Figures 3 and 4.
Note 6: A 65Ω pullup resistor is connected from OUT_ to 5.5V. Rising refers to V
OUT_
when current through OUT_ is turned off and
falling refers to V
OUT_
when current through OUT_ is turned on.
