May be a bit expensive if they do turn out to be flakey. Rare Though I haven't gotten a chance to use these I'm glad I got these rare beauties. I've got a old 7 segment multimeter I want to retrofit. My husband and I use them a lot in our projects. I was highly satisfied with my order. Everything works great and we were able to make amazing project!

The seller take care about packaging good, and everything came in very good shape, no damages at all, small wires are straight. We will order more of those drivers for our projects for sure. Not recommended. Received these ICs today, and I'm disappointed. More than half of them have bent pins from being carelessly inserted into the foam pad that they come on. I don't even know if they work yet - I'll update this review after I test them.

Whether they end up working or not, I can't recommend buying these. These pins on some of these ICs are just too damaged. Only registered users can write reviews. Please log in or register. YES NO.

I ve ordered 10 ICs and all behave the same. Do you think the ICs are broken. If so what IC or vendor would you recommend? Here is the data sheet i connected to my Nixie Clock and ABCD to ground or 5V, but any time 0nly pin 0 and 2 works at the same time.

And i want to use an Arduino, but i think this is te right forum, cause i posted it under General Electronics? You must apply valid 0 or 1 inputs to all 4 pins, A B C and D, because the decoder blanks invalid codes. OP , Do you have a datasheet or part number or vendor link for the Nixie tubes? Can you post a photo of it? Your description is not easy to follow but a small voltage is not a bad sign.

These chips sink, not source. If you are playing around with a led to test the chip, you must connect the led between Vcc and the pin under test with of course a current limiting resistor say R. Obviously, during such experiments, there must be no high voltage active. I believe we have asked for a schematic Reply 1 and still don't have one. Now that you mention it, the very fact that the OP is even measuring voltage suggests he's trying to source instead of sink.

If he were sinking he wouldn't be measuring voltage, he would be putting a meter in series and trying to measure current.

Control key as very useful service. It won't meet hopefully manually importing. There a variety is not discussed, very solid threaded from your current.

This one I got from Jan :. Ok, lets go to the Sketch I made for my tester. It's so simple, that there is nearly nothing to explain. Just some words: The 2. On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs of the controller. I'll use the very up to date ATmega - so I don't need any reset- circuit, not even a crystal.

The button switch switches between the different test modes I'll explain later and finally the 3 LEDs show the test results. The ATmega is totally cool!!! I will use it for all my clocks in the next future because you need no other parts around it! You only have to put in the test-IC. When the green LED lights up, it's a good When the yellow LED lights up, it's a good When holding the button for longer than one second you come back to the free- running mode.

I got many hints from the Neonixies Gang that in some cases a defective may leak at the outputs. I never took used for my project, so I haven't thought about that this also can happen. I had to change my circuit to this second revision, that works with a ZM.

The ZM tube is driven with 2mA current. The V plus tube and resistors with the voltage dividers make it possible to detect a too high leakage current in case the IC is defective. Moreover I have a good control with the tube whether the test- IC really works. So I added a IC. So is it 8mA. In that case that would explain why it does not work.

Is it possible to do a dry run with LEDs. I can findthe resistor that will limit the current. The question is is the LED going to lit then? Although I find off state confusing, unless they mean low. My point still stands though, too much current. I would have thought the current would not be larger then the current that flows through the nixie tube. Nixie tubes have a different characteristic to LEDs. LEDs need current limiting resistors to the current you want. Lots of discussion on here about LED current limiting resistors, do some searching.

I thought the current flowing through the led would be smaller expecially with current limiting resistor, then the current flowing through Nixie tube causing glow discharged. I will try to connect it with nixie tube as intended. I attach the diagram I intent to use. Not sure how to post the image so it shows in the body of the message.

My data sheet states that the "drives gas filled indicator tubes directly. In the diagram I posted there is 20k resistor used. I have seen other connection diagrams where they used smaller resistors. So I hope I will not fry yet another chip and Arduino Nano:.

Yes, there needs to be a way to completely exclude them from Google searches. Particularly when they generate - as they do - spurious results. Gotta stop using old obsolete parts. You guys must be using it wrong. Its my prime place for all semiconductors, including industrial stuff. Do you read the results of a search and use your brain to decide on what to look at? Are thouse faulty chips or am I doing something fundamentally wrong. I attach the photos.
