1 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 0.1ns to 1s.

2 Hysteresis of 250 mV is guaranteed over all operating conditions when hysteresis is enabled.
