NI9401 inputs: pull-down and Schmitt trigger?

Hi,

I am using NI 9401 module as part of a throttle body control / data acquisition platform with a cRIO 9053.

I have found in other posts that the NI 9401 has a built in 47 Kohm pull-down resistor.

Does it include a Schmitt trigger for squaring up the waveforms?

The reason I ask, is our existing SENT interface circuits include a Schmitt trigger, as many SENT sources are not very square. 

The NI 9403 module indicates a pull-down resistor and Schmidtt trigger are included - but this note is not the  N9401 doc. 

The 9401 and 9403 doc both include the same block diagram of protection and buffer circuitry.

I chose against the NI 9403 module as it's update rate is 7usec - too slow for the 3usec clock rate for the SENT signals that need to be read  (NI 9401 is 0.1 usec).

Thanks!
