I think only Panaplex tubes (or the very rare 7-segment round tubes) would be usable. This chip has 7-segment display integrated in it, decoding it to 10 open collector/drain driver would require a large logic circuit or an Arduino or other uC. But then using this chip would make little to no sense. The CT7002 has BCD output, which would make it much easier. So, shortly speaking - for driving normal nixie tubes you need to get CT7002 to avoid complications. But if you decide to go 7-segment, there is few schematics in this datasheet of how to drive plasma displays (panaplex) or fluorescent (VFD). https://proaudiodesignforum.com/images/pdf/CT7001_Cal-Tex_Clock_IC.pdf You could also go for the old type LEDs - low brightness, but beautiful shade of red - something like displays from this page: http://www.industrialalchemy.org/tubepage.php?item=33&user=0 Funny thing is it uses negative supply! So crossing this with any other logic (for example, 74141 for CT7002) will require careful designing... -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
