ADuM320x, ADuM340x Schmitt trigger inputs?

Dear colleagues!

ADuM320x, ADuM340x  datasheets' functional block diagrams denote Schmitt trigger inputs. Unfortunately nether input hysteresis voltage nore input rise/fall time are mentioned in further specifications. Do these devices really have Schmitt trigger inputs? If so, how slow can be input voltages? How it affects the power dissipation?

Thanks!
