CD4017 Decade Counter IC (SMD Package)

The CD4017 counts through its ten outputs one at a time with each clock pulse, a simple but widely useful building block for LED chasers, sequencing circuits, and basic timing logic without needing a microcontroller. This SMD-package version carries that same function onto a compact surface-mount footprint, meant for a finished PCB design rather than the breadboard-friendly DIP-16 version already in the catalog.
