EC312 Digital Input and Output info

I need information on max VDS, Max constant current sink, and any rating for ESD/EFT tested on the GPIO port of EC312. Is there a more detailed spec available for the expansion?
Dear Customer,

I'm checking with R&D team and will come back to you later.

Best regards,
Victor
