Frequently Asked Questions
What is the maximum clock frequency the HCF4017BE can handle at its nominal supply voltage?
At its nominal supply voltage of 10 V, the HCF4017BE is specified for a maximum clock frequency of 2.5 MHz. At lower supply voltages such as 5 V, the maximum frequency is reduced due to higher propagation delays typical of CMOS 4000-series logic, so designers should verify timing margins when operating at the lower end of the 3 V to 15 V supply range.
How can the HCF4017BE be configured as a divide-by-N counter for less than 10 stages?
By connecting one of the decoded outputs (Q0 through Q9) back to the RESET pin, the HCF4017BE resets to zero after reaching the selected count, effectively creating a divide-by-N circuit with N ranging from 2 to 9. For example, connecting Q5 to RESET generates a divide-by-5 function, producing a pulse at the CARRY OUT pin every 5 input clock cycles, which is useful in frequency-synthesis and timing applications.
Is the 16-pin DIP package of the HCF4017BE compatible with standard 0.1-inch breadboards and older PCB tooling?
Yes, the HCF4017BE uses a 16-pin 0.6-inch wide DIP (PDIP-16) package with 0.1-inch pin spacing, which fits directly into standard solderless breadboards and matches through-hole PCB footprints used since the early 4000-series logic era. The 0.0036 A (3.6 mA) output sink current is sufficient to drive individual LEDs with a current-limiting resistor, making it a straightforward choice for educational and hobby circuit assembly without soldering expertise.
