3.3V TIMING CHARACTERISTICS
(V+ = +3V to < +4.5V, AGND = PGND = 0V; all voltages are measured with respect to PGND, unless otherwise noted. T A = T J = -40°C
to +125°C, unless otherwise noted. Typical values are at T A = +25°C.) (Notes 1, 5)
6
Note 1: All devices are 100% production tested at T
Note 2: Guaranteed by design, not production tested.
Note 3: Parameter is measured at trip point of latch with V
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
