3.3V TIMING CHARACTERISTICS
(V+ = +3V to < +4.5V, AGND = PGND = 0V; all voltages are measured with respect to PGND, unless otherwise noted. TA = TJ =
-40°C to +125°C, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 5)

Note 1: All devices are 100% production tested at TJ = +25°C and +125°C. Limits to -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 VFB = 0V.
Note 4: Gain is defined as A = ∆VCOMP / ∆VCS, 0.05V ≤ VCS ≤ 0.25V.
Note 5: See Figures 3 and 4.
Note 6: A 65Ω pullup resistor is connected from OUT_ _ to 5.5V. Rising refers to VOUT_ _ when current through OUT_ _ is turned off
and falling refers to VOUT_ _ when current through OUT_ _ is turned on.
