I've just hooked up a MAX6921 to an IN-12A nixie on a breadboard. From what I can see, it works just fine, even with all the cathodes turned off at once. Admittedly the 76 volt maximum supply voltage seems at first to be too low for a nixie, but as gregebert says, the full anode voltage doesn't necessarily appear across the driver, and in practice 70 volts seems to be enough to switch the tube completely off. Sinking current back into the rail doesn't seem to hurt it much either. Is there anything particular that puts you off using MAX69** parts to drive nixies? If I've missed something, I'd rather know about it before I buy PCBs! I won't dismantle this breadboard yet because I still need to do more work on it, so if there are any measurements you think I should take, I'd be interested to hear about them.
