Also the ULN2003. Similar part. Some of these older technology parts are getting harder to find. Terry On Monday, February 26, 2018 at 3:30:05 PM UTC-6, Terry S wrote: > > Makes a good relay driver as well. > > On Monday, February 26, 2018 at 3:21:40 PM UTC-6, Dekatron42 wrote: >> >> The

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. /Martin -- You

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. On Monday, 26 February 2018 18:55:31 UTC, nixiebunny wrote: > > I use the TD62083 in my Nixie watch. The TD62084 is the 5V input version. > It needs a 50V Zener diode on the common diode pin. > > > On

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. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To
