The LV family does not have internal hysteresis. Due to the wide effective bandwidth and low input offset voltage, it is possible for the output to "chatter" (oscillate) when the absolute differential voltage near zero, as the comparator triggers on it's own internal wideband noise. TI recommends that the user add external hysteresis if slow moving signals are expected. See Section 7.1.2 in the following section.
