Can each side of the Si84xx digital isolators be powered from supplies operating at different voltages? For example, can I operate the A side at 5V VDD and the B side at 3.3V VDD, and vice versa?

Yes, as long as the two sides are operating within their specified operating range (2.6V to 5.5V), the A side and B side supply pins can be powered from different supply voltages.This capability allows the Si84xx to be used as a LOGIC level translator.
