CCS/UCD3138: I hopping to know ,does UCD3138 IO pin have Clamp diode?

Not only digital pin ,such as  ADC pin or Gpio and so on .

Or  UCD3138 Which Pin have Clamp diode and  ESD protection function？

Or have any  reference design to protect  UCD3138 input an  output Voltage？

Thank you very much！

Thankyou for you answer, in this part of the datasheet is Layout Guidelines.And it suggest us to add the Schottky diodes.But I didn't found it say the UCD3138 all pin have already have the diodes.

So I am not sure should we add the Schottky diodes from outside Circuit? Or All pin have already have schottky diodes in UCD3138? This is some confuse about the datesheet. I am very Appreciate for you answer.
