Devices with Schmitt-trigger inputs do not have static V_IL/V_IH values. The positive-/negative-going threshold voltages are specified in section 6.7; for the worst case, you can use V_T−(min)/V_T+(max).

See the application report Understanding Schmitt Triggers (SCEA046) and the training video Understanding schmitt trigger.
