Some issues for DOUT pin of ADT7301

Hi,       

      My Client used ADT7301, As following is their schematic for ADT7301.

       

       Due to the pull-up resistor, ADT7301 has ~1mA sink current from DOUT pin. Therefore, they have two questions to clarify.

  1. Does this sink current have a chance to damage DOUT pin or Chip?
  2. Can this sink current affect temperature accuracy? 

       I can't find more description of specifications for DOUT pin in datasheet or other document, so I can't clarify these issues to my customer, please help me, thanks.
