The Nexperia 74HC4017D,652 is a 5-stage Johnson decade counter from the 74HC family, packaged in a 16-SOIC footprint. It counts up to ten decoded outputs with a maximum count rate of 83 MHz, making it a workhorse for sequential logic, frequency division, and LED chaser circuits in industrial control, automotive modules, and general-purpose digital designs. The asynchronous reset pin lets you clear the count immediately, which is handy when you need a known start state after a power-on glitch or a watchdog timeout.
The 2 V to 6 V supply range means this part plays nice with both 3.3 V and 5 V logic families without a level shifter in most cases. At 2 V it's still functional, though the 83 MHz count rate is specified at the higher end of the supply — expect slower operation near the lower rail if you're pushing the clock.
