TMP422-EP: TMP422 VID V6211618 Digital Inputs

The TMP422 VID V6211618 specifies SMBus parameters and Digital Input parameters.  The TEM422 has no inputs other than the SMBus and DX pins.  I assume the DX pins are analog and not the Digital Inputs referred to in the VID.  My assumption is that the Digital Inputs in the VID are residual from the TMP421 spec that has external address pins.  Is this assumption correct? 

If the DX pins are the Digital Inputs, how can VIH/VIL be verified, and it is safe to perform the leakage tests as specified for the Digital Inputs on the DX pins?

Thanks,
