## Description

The CD4017 is a CMOS decade counter/divider IC that sequentially activates one of ten outputs (Q0–Q9) on each rising edge of the clock input. Widely used in LED chasers, sequencers, and timing circuits, it's one of the most popular CMOS logic ICs for hobby electronics. The IC features a clock input, clock enable, and reset pin, making it easy to build sequential circuits with minimal external components. Each output goes high in turn while all others remain low. Key Features Decade Counter – 10 decoded outputs (Q0–Q9), one active at a time Carry Out – Cascading output for chaining multiple counters Clock Enable and Reset – Full control over counting sequence CMOS Logic – Low power consumption, wide voltage range Specifications IC Number – CD4017 / HEF4017 Package – 16-pin DIP (through-hole) Supply Voltage – 3V to 15V DC Logic Family – CMOS Ideal For LED chaser and sequencer circuits Frequency dividers Timer and counting applications Educational logic circuit projects Package Contents 1× CD4017 Decade Counter/Divider CMOS IC
