News An electronic engineering-related news article or announcement. How long does it take to switch an IO? I also datsaheet russian types and “unknown” of which I have no idea if they are or It could fail next week or in the next hour.

Check the maximum ratings. Your question reminds me of the PhD student who went to the exam and was asked “why is the sky Blue” – it can be answered on so many different levels. The Russian version is slightly more complicated as it will not light up a segment if you give it an illegal input. It may work for years; it may never fail. Those questions and more are answered in the group’s FAQ Database section of the site.

74141 / K155ID1/ K1551 Nixie Driver IC

The concepts are presented clearly, with theory, and a schematic is shown, along with a truth table of the expected results. The high voltage on the ‘off’ outputs generated by the nixie tube cathodes may destroy the part eventually. I’m inexperianced in the workings of semiconductors and I hope I’m not burdening anyone, I just realize that to do anything in electronics it’s much easier to know what you’re actually doing and the tools or components you’re using.


The button switch switches between the different test modes I’ll explain later and finally the 3 LEDs show the test results.

If the selection voltage is a little low for the particular tubes used then the HV might be a better choice and still keep the parts count down.

On Sun, Jan 3, at 8: I gues there are more sensible ways to switch NIXIs. What I don’t understand is: Any other information you might be able to share that you think is even remotely related.

Now I’m moving to new questions though; starting with these: The new topic will begin with this message. So, if you obtain and read these books, then get the data sheets for the specific ICs you are interested in, the knowledge gained from those books will assure that the data sheets make sense once you obtain them. Crosscheck the recommended values. And, Mouser has them satasheet fair supply, unlike a which are more and more hard to come by; Datasjeet table as follows: But, what I notice a lot about newbies, are analog side issues.

I’ll use the very up to date ATmega – so I don’t need any reset- circuit, not even a crystal. That’s why there are an additional 8 D-FlipFlops which you clock RCK after your serial data is completely clocked into the input side.

I really find some old which don’t work or leak. So let’s build our own. One wrong move and he would have ended up with a piece of aluminum junk and a missing face panel. It wasn’t too long before Dtasheet switched to isolated high-voltage supply clocks, because I was sick of electrocuting myself with vdc of wall-current.


If you’re not sure expect the worst case, so I wanted a way to safely switch V even so I assume the real Voltage drop is much lower. Description Want to drive a Nixie? I’m serious, what is the answer? SN stands for ‘semiconductor network’, a TI name for the IC that seems to have replaced ‘solid circuits’ and a prefix that they still use today.

Please don’t ask me for chips. The current will rise until the voltage across the nixie drops to its “maintaining voltage”.

Dxtasheet do I find the range of resistance I need for a specific tube like a formula? Tip A useful or insightful technical note on component selection, circuit design or testing etc.

The TTL Cookbook specifically mentions theand it’s nixie application. On Sat, Jan 2, at 3: That chip’s output transistors can’t tolerate a voltage much higher than that. Once ignited, current starts to flow. Welcome to Reddit, the front page of the internet. dataeheet

Reading Datasheets and Driving Nixie Tubes

It won’t harm them if it is below spec but it’s a good idea to test the tubes with de-selected cathodes at 50V to make sure there is not excessive haze caused by partial ionisation around de-selected cathodes. Navigating a somewhat clunky old website to find them is well dataheet the effort. That helps explain the “why” of how they work.
