Key Features
- Johnson counter with 10 fully decoded outputs providing direct single-pin output for each count state without external decoding logic
- Gated clock input (clock enable/inhibit) allowing easy counter cascading and synchronization in multi-stage sequencer designs
- High-speed HC CMOS technology in compact 16-pin TSSOP package combining fast operation with minimal board footprint
Applications
The CD74HC4017PWR is widely used in LED chasers, light sequencers, and decorative displays where each output drives one LED in a sequential scan pattern. It is also applied in frequency division circuits, time-slot multiplexers, and event sequencers for industrial control and consumer electronics. The 10 decoded outputs make it particularly useful in clock-driven state machines and digital pattern generation applications.

Frequently Asked Questions
How many decoded outputs does the CD74HC4017PWR have?
The CD74HC4017PWR has 10 fully decoded outputs (Q0 through Q9), one for each count state of the Johnson decade counter. This eliminates the need for external decoder logic, simplifying designs for LED sequencers, displays, and event timing circuits.
Does the CD74HC4017PWR have a clock enable input?
Yes, the CD74HC4017PWR features a gated clock (clock inhibit) input that can halt counting without resetting the counter state. This enables easy synchronization, cascading of multiple counters, and power-saving pause modes in sequential control applications.
What package does the CD74HC4017PWR use?
The CD74HC4017PWR is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package), JESD-30 code R-PDSO-G16. This surface-mount package is compact and suitable for modern PCB designs with high component density requirements.
What logic family does the CD74HC4017PWR belong to?
The CD74HC4017PWR belongs to the HC/UH high-speed CMOS logic family. It operates with standard CMOS supply voltages and offers high noise immunity and low power consumption, making it suitable for both portable and industrial digital logic applications.
