integrated circuit - What is a modern SN74141 alternative?



I'm making a Nixie Clock and I had to buy from ebay some old SN74141 (KM155ID1 equivalent). Is there some newer IC which does the same things as this one, or similar, that I could get from big suppliers like Mouser, LCSC or DigiKey?



Answer




Use discrete transistors- MPSA42 is an old TO-92 part but easily available. Rated at 300V. Or MMBTA42 if you prefer SMT. For example, from this website:
