I use five HV5622 high voltage shift registers to drive 14 nixies, this only needs 3 digital outputs of the mcu, 4 if you also use the blank signal (e.g.; for dimming). Not cheap but it works fine.
The downside of this approach is that, to be in spec, you need a 12V rail. However, it should also work with 5V. Craig Garnett schrieb am Dienstag, 12.

If I were to run the tubes static, how would I go about driving 120 cathodes? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
