I wouldn't design a clock without a full datasheet; this looks like a totem-pole output driver, and the internal design of a chip that can do that at high-voltage is not trivial.
I looked at the offerings from Supertex, and their 64-bit push-pull driver IC can only run up to 180V, which is marginal for nixies. Maybe TI did a custom IC for plasma displays (guessing here, based on the SN part number prefix), so a full datasheet may not be publicly available. The funny thing here is when I do a parametric search for SN75151 on ti.com, it pre-hits to SN751518, but does not offer-up a datasheet. So I think there's something on their website, but not for public access. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
