From the Spec, we can see the VIH and VIL has the relation ship with VDD.
My question is that VDD may be different in worst, best and typical case, such as 0.9V,0.7V and 0.8v.
Is VIH or VIL different in these three case or just use the typical VDD 0.8v?


Thanks

They should be varied according to your VDD value.
