We added the 74141 BCD-to-Decade decoder, nixie tube driver to our Eagle parts library. This device makes it easy to control nixie tubes by sending binary codes to light up a specific number. This part went into our nixie thing for Maker Faire, the PCBs should be in this week some time.
Considering nixie tubes went out of vogue in the early 1970’s where would you source them? 7-Segment LED displays were common on the newer pocket calculators in 1974 and nixies were relagated to desktop units.but concidered old technoogy then! A nostalgia project could be fun with a Steampunk twist if nixies were available!
Tell us where to find them!

ebay? loads of them there… both tubes and 74141’s (or the russian equivalent K155ID1)
Is there a SMD equivelant to the 74141?
I thought they were less reliable than the nixies?
Dont think you will find 74141 in SMD package, if you want smd probably easiest to use transistors
There’s loads of them streaming in from former soviet block countries. I’ve never had many problems with the kd155s made for USSR military in the 80s. Some of he old ones will pop on static frequently though. Can be quite a shock if you are only used to modern static resilient chips. Lol…
Also… probably none of these ever made in smd. I have only seen dip.
Thanks for the replies! I’ll probably use my own SMD solution :)
Does the KD155 have the same pin out as the 74141?
As far as I know they are exactly the same.
How I can download 74141 part for use it in eagle library?
Thank you
It’s already available in the Eagle standard libraries named 74xx-eu and 74xx-us
Hi I was wondering if the chip 74hc42d is equivalent to the 74141.
Thanks.
