DC Electrical Characteristics
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. VIL and VIH do not apply
when hysteresis is enabled.
Hysteresis of 250 mV is guaranteed overall operating conditions when hysteresis is enabled.
