To maintain a valid level, the transitioning edge of the input must sustain a constant slew rate (monotonic) from the current DC
level through to the target DC level, VIL or VIH. Monotonic input transition time is from 0.1 ns to 1 s. VIL and VIH do not apply
when hysteresis is enabled.
Hysteresis of 350 mV is guaranteed over all operating conditions when hysteresis is enabled.
