Design a Custom BoardAbout This Component
The HEF4017B is a 5-stage Johnson decade counter providing ten decoded active-HIGH outputs (Q0–Q9) plus carry output, suitable for frequency division and sequencing applications. It features dual clock inputs with Schmitt trigger tolerance, asynchronous reset, and automatic counter code correction. Operating from 3V to 15V with CMOS low-power characteristics, it's ideal for cascaded counting, timing control, and sequential logic circuits.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
