Frequently Asked Questions

What is the maximum clock frequency CD74HC4017PWT can handle, and at which supply voltage?

CD74HC4017PWT can be clocked at up to 20 MHz when operating from its rated 2 V to 6 V supply range in the HC/UH CMOS family, with a 50 pF load capacitance, making it fast enough for most sequential LED, relay, and timing applications without additional buffering.

How does the Johnson counter architecture of CD74HC4017PWT simplify LED sequencer circuit design?

The CD74HC4017PWT uses a Johnson counter with 10 individually decoded outputs so each output goes high in turn on successive clock pulses, eliminating the need for an external decoder IC. This reduces BOM count and allows direct connection of up to 10 LEDs or small-signal loads across the 2 V to 6 V supply.

Which industrial or consumer applications does CD74HC4017PWT suit best?

CD74HC4017PWT is ideal for LED chasers, scan matrix controllers, frequency dividers producing divide-by-10 outputs at up to 20 MHz, and step-sequence controllers for small pneumatic or solenoid systems. Its 10-decoded-output structure also appears in display multiplexing, gaming light patterns, and educational digital logic trainers.

When is the 16-pin TSSOP package of CD74HC4017PWT preferred over a DIP alternative for a new board design?

The 16-pin TSSOP package of CD74HC4017PWT offers a footprint roughly 65% smaller than an equivalent 16-pin DIP, which is advantageous when PCB real estate is constrained, such as in handheld consumer gadgets or compact industrial panels where SMT assembly is already in use and through-hole components add cost.
