The core of the 4017’s datasheet is the logic diagram. The chip is a synchronous 5-stage Johnson counter with a built-in decoder. It features 10 fully decoded outputs (Q0 to Q9), one clock input (CLK), a clock-inhibit pin (INH), a master reset pin (MR), and a carry-out pin (CO). The Johnson counter architecture ensures that only one output is high at any given time, while the other nine remain low. This “one-hot” encoding simplifies driving LEDs directly without external decoding logic. 4017 counter ic datasheet

The 4017 is a 5-stage Johnson counter that converts a clock input into a sequence of 10 high-state outputs. The CD4017 is designed for low power consumption
