Also the ULN2003. Similar part. Some of these older technology parts are
getting harder to find.

The SN75468 or SN75469 are two of my favourites, hooking up the COM pin to
some 60V via a resistor divider or zener and resistor works beautifully.
I've seen it used with Burroughs Nixies and Burroughs Bar Graph displays.
It has been used by a bunch of people here too.

This is placing a zener diode between power and ground to conduct above a
trigger voltage?

Even though the nixies operate around 170V, they provide some voltage drop
so that the driver doesn't see the full 170V. If you use a driver rated at
a lower voltage, you want to provide protection as Mr. Forbes does (the
zener diode) so that the driver doesn't get stressed from leakage
The watch tubes have a much lower voltage requirement? I thought ~170V was
the usual level.

What driver chips have you used besides 7441 or 74141 in direct drive mode
for your Nixie projects?
I've used Max69** chips with VFD projects but have not found a good Nixie
driver chip yet.
