Datasheets are not always easy to read, especially when you’re not too familiar with the technical background. It could fail next week or in the next hour. How long does it take to switch an IO? More importantly, the output drivers of this chip are designed to handle the high voltages involved in driving Nixie tubes.
All are tested now. Log in or sign up in seconds.
What about the timings? In this fast-paced time of speedy processors, and all sorts of things only dreamed of when those books were written, one can still get right down to each binary bit, and where it goes, and exactly what it does.

Nixie driver ICs 74141
It was mentioned in the email you should have received upon joining, if you provided a working email address. Ok, lets go to the Sketch I made for my tester. That chip’s output transistors can’t tolerate a voltage daatsheet higher than that. A useful or insightful technical note on component selection, circuit design or testing etc. Go read a book k155d1 “Bebop to the Boolean Boogie” — great book that really tries to make you rethink how electronic design works.
As always, see you next week.
Reading Datasheets and Driving Nixie Tubes
In that case use a level shifter. Check out our Nixie tube project list! This one I got from Jan: No contracts, No fees, No Kidding! Nixie Tubes have an anode voltage of around V.
Fritzing Project – Nixie Clock & Display
High voltage duties are handled by a modular HV power supply which bumps 9V up to the required V. The entire assembly mounts inside a tiny glass jam jar, giving it the effect of being a vacuum datssheet. Because of this, all we care about is the sinking capacity because of our usage in this case; the transistor should be able to handle the load fine, voltage is irrelevant. I know they are ish but I’m not sure if the pins are the same.
According to common sense and your experience it should work, but it’s out of specs. It may work for years; it may never fail. That helps explain the “why” of how they work.
If you completely omitted the limiting resistor, your nixie would have a VERY short and eventful life. The TTL Cookbook specifically mentions theand it’s nixie application. Ok, so I’ve found a schematic I like, it doesn’t, datasheey, use either of the ICs we have reviewed kinda rude I know, didn’t intend on that happening, circumstances just made it that way.
Yes, delete it Cancel. I guess this is what I get for writing rants late at night: I’m sure one of you’ve heard of this version. The Russian k1155id1 seem to clamp at a higher voltage. Use Ohm’s law to get a good idea of the resistor value you will need, and then fine tune it from there.
