TEXAS INSTRUMENTS 10pcs/lot CD4017 CD4017B CD4017BE 4017 Decade Counter Divider IC New Original

Used just to design led circuits. They work, they preform.

I love this chip so much. Easiest way to include a counter in your project! Would buy again compared to buying from Digikey or Mouser.

Used most of these now and none failed. Will buy again.

I ordered this to repair a weather station rain gage. These chips are good quality not fakes and packaged well

If you find the RIGHT schematic online, this LED chaser and return circuit is pretty cool. Problem being a LOT of circuits online call their circuit the KITT “chaser light”. But hooking it up, it only goes one way, then repeats (like left to right; 1,2,3 and starts 1,2,3 again). KITT’s light went 1,2,3,2,1,2,3…etc (or left to right, then back left, and THEN repeating)..
