I also have some data- sheets for the different types: Block Diagram for This one I got from Jan: Ok, lets go to the Sketch I made for my. Category. Description, Bcd-to-decimal Decoder/driver. Company, Texas Instruments, Inc. Datasheet, Download SN datasheet. Quote. Find where to buy. Simplifies driving Nixie tubes. Brand new Russian ICs, U.S. equivalents with overrange digit blanking. ENGLISH DATASHEET: DATASHEET PAGE 1.
When the yellow LED lights up, it’s a good 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. I never took used for my project, so I haven’t thought about that this also can happen. The button switch switches between the different test modes I’ll explain later and finally the 3 LEDs show the test results.
The ZM tube is satasheet with 2mA current. I will use datasheey for all my clocks in the next future because you need no other parts around it! I got many hints from the Neonixies Gang that in some cases a defective may leak at the outputs.
Ok, lets go to the Sketch I made for my tester. All are tested now.
Nixie driver ICs 74141
The ones I have I will use for my next projects. You only have to put in the test-IC.
This one I got from Jan: I also have russian types and “unknown” of which I have no idea if they are or Moreover I have a good control with the tube whether the test- IC really works. Check the different truth- charts!!! I sat down and sketched a “super simple” driver- testing circuit to test them all. The russian types have high “off” voltage approx Vso the efficiency is much dtasheet, and the “Blue Spot” problem can not occur e. Please don’t ask me for chips. Truth Table for the, A and B Chip.
I really find some old which don’t work or leak. My other projects took away a lot of time, so I decided to give it to a friend of mine to do the coding.
When holding the button for longer than one second you come back to the free- running mode. On the right side you also see 10 transistors which only have the job to drive the LEDs and the datasjeet of the controller.
