ADuM7234 input hysteresis

The ADuM7234 functional block diagram in the datasheet indicates Schmitt-trigger buffered inputs, however this is not reflected in the electrical characteristics specification section.

I would like to use passive shoot-through prevention at the inputs, and would like to characterize the inputs of the device.

1. Are the inputs indeed Schmitt-trigger buffered?

2. If so, what are the threshold and hysteresis specifications?
