*
The maximum input rise/fall time is related to the noise induced into the input buffer trace. If the noise is low,
then the rise time and fall time of input buffers can be increased beyond the maximum value. The longer the
rise/fall times, the more susceptible the input signal is to the board noise. Actel recommends signal integrity
evaluation/characterization of the system to ensure that there is no excessive noise coupling into input signals.
