This is not exactly an answer to your question, but -- I thought I'd share m findings. I was looking for something that would let me drive nixies through a serial interface. The best I could find was the MC33999. It won't replace the 74141s, because of 50V max output drain voltage, but it might save some circuitry if somebody wants to direct-drive nixies through a serial/SPI connection. While searching, I also found the MCP23S18 (SPI) and MCP23018 (I2C) I/O expanders, which could also be useful. You still need a driving transistor + resistor per cathode. In my current design I decided to go with 74HC595s and 74141s; with 6 nixies you still need two 16-bit chips anyway, so three 595s are not a big deal. --J. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
