Hi Takishin-san,

By pull-down resistance value, I assume you are talking about the parallel data inputs?

I do not have a DS90C185 on hand at the moment, but I was able to probe the inputs of the DS90C187 on a C187EVK01. The pull-down resistance values I measured were around 130 kOhms.

Regards,

Michael
