Can you multiplex a Nixie display in the same way as a

never seen it done, but that certainly doesn't mean it isn't possible.
If you don't mind direct drive, there are TTL BCD-to-10 decoder chips
intended specifically for driving Nixie tubes. I just looked in my
newer databook at the 7445 and 74145, and they don't *say* "can directly
drive Nixies", but they do have high-voltage open-collector outputs.
These "HV" decoders have 30 and 15 volt output devices. The one for neon
lamps or Nixies was the 7441.
