About AD5254 Input and output Digital Voltage

Hi,

My customers are considering using the AD5254.
So I got a question.

What voltages can I apply to the SCL pin and how many A can be applied?
"Digital Inputs and Output Voltage to GND" is stated as "0 V, 7 V", is this the same idea as the one confirmed previously by the AD 5290?

AD5290 Digital Input and Output Voltages to GND @ AMR
