| Market Reality | The CD4017 is the LED chaser: a divide-by-ten Johnson counter with ten decoded outputs that walk one at a time - the chip behind running lights, sequencers, toy logic and a hundred beginner circuits, still sold in the millions as kits, and still repaired on old appliance and signage boards. The 4000B ecosystem makes sourcing calm: HEF4017, MC14017, TC4017 and the whole letter-soup row are the same die and pinout by standard. The one real confusion sits next door - the CD4022, its divide-by-eight sibling in the same 16-pin body with a different output pin map. Same family, same controls, different dance. | The CD4017 is the LED chaser: a divide-by-ten Johnson counter with ten decoded outputs that walk one at a time - the chip behind running lights, sequencers, toy logic and a hundred beginner circuits, still sold in the millions as kits, and still repaired on old appliance and signage boards.
