{"title":"4017 Decade Counter/Divider CMOS IC","handle":"4017-decade-counter-divider-cmos-ic","url":"/products/4017-decade-counter-divider-cmos-ic","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.\n\nThe 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.\n\nKey Features\n\n\nDecade Counter – 10 decoded outputs (Q0–Q9), one active at a time\n\nCarry Out – Cascading output for chaining multiple counters\n\nClock Enable and Reset – Full control over counting sequence\n\nCMOS Logic – Low power consumption, wide voltage range\n\n\nSpecifications\n\n\nIC Number – CD4017 / HEF4017\n\nPackage – 16-pin DIP (through-hole)\n\nSupply Voltage – 3V to 15V DC\n\nLogic Family – CMOS\n\n\nIdeal For\n\nLED chaser and sequencer circuits\nFrequency dividers\nTimer and counting applications\nEducational logic circuit projects\n\n\nPackage Contents\n\n1× CD4017 Decade Counter/Divider CMOS IC\n","vendor":"Little Bird","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":8910,"title":"Default Title","sku":"TB-ZC4017","price":1.45,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
