The HV5530 works well with normal nixie tubes (not B7971). You also could use HV5122/5222 (cheaper), they are 200V rated, but thats enough for nixies. Yes these chips need 12V supply and logic, but people have reported that they work with 5V logic signals. I have used a level-shifter.
I use HV5122 in my current project: See here... <http://swissnixie.com/projects/SUNIX-S/SN_SUNIX_S_R1.2_WTB_SCHEMATIC.png> "Level Shifting" is translating 5V to 12V logic level. The ST66 chip can producte 12V 30mA from 5V, if there is no 12V available. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
