I want to design a nixie clock based on a high voltage shift register: the HV5530. I don't what to multiplex the tubes to avoid loss in brightness. My idea is to leave the anodes powered all the time and switch the cathodes by connecting them directly to the outputs of the HV5530. I will use a ribbon cable to connect the tube driver to the board that holds the tubes.
Should I worry about any inductive effects of the wires and the traces on the PCBs? Should I use some voltage clamps or will it work by simply connecting the cathodes directly to the chip?
