So I was originally looking at the Microchip HV513 <https://www.microchip.com/wwwproducts/en/HV513>. It's a 250V totem pole driver with 5V input logic and a latch. Was going to do a quick sketch of what I had in mind for the output, but haven't had the time to get round to it.
I was planning to not multiplex my nixies, probably leaving all cathodes connected directly to the HV line, and placing current liming resistors on the cathodes. Was interested to see if I'd need to tweak any of the individual resistor values uniform current/brightness. If I implemented only a low side switch, I was looking at something like the MMBTA42, available from a few manufacturers and is good for 300V, but I haven't yet found any information about leakage currents when the device is off. Alternatively I think I found a mosfet or two with sufficient V(DS) and logic level switching, but I need to recheck the D-S leakage. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
