Alternatively, you can also use discrete BJT's or MOSFET's to drive your cathodes. If you have a multiplexed design (so you would e.g. only need them for driving 2 nixies at a time in a 6 digit clock) it's quite doable and probably cheaper/simpler/cleaner than using that HVXXXX chip + level shifters. You can also consider using the SN75468, with a zener on the common (pin 9), as shown here: http://lucsmall.com/2011/07/19/using-the-sn75468-as-a-nixie-tube-driver/
If you don't have enough pins on your MCU, you'd need a shift register (e.g. a 74595). Or just get an MCU with more pins, they're cheap anyway. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
