4017 IC Flip-Flop Decade Counter/Divider

4017 IC Flip-Flop Decade Counter/DividerThe CD4017BE functions as a decade counter and provides ten fully decoded outputs. When a clock pulse enters the IC, it advances the active output pin to the next in sequence, starting from Q0 up to Q9. This sequential switching makes it perfect for LED chasers, event counters, and timing circuits.You can reset the count using the reset input or control the sequence using the clock enable input. The CD4017BE outputs a logic HIGH on one of its ten outputs at a time, depending on the clock count, and the sequence continues until a reset occurs. Its CMOS architecture ensures low power consumption, and its compatibility with both analog and digital systems enables broad integration. You can power the IC with a wide voltage range (3V to 15V), and its output drives standard TTL logic levels, LEDs, or other CMOS inputs directly.Key Features10 decoded outputs (Q0 to Q9)Counts on positive clock edgeBuilt-in divide-by-10 counterAsynchronous master resetClock enable controlWide voltage supply range (3V–15V)Drives LEDs or logic circuits directlyLow power CMOS designDIP-16 packagePin Configuration (DIP-16)PinLabelDescription1Q5Output 52Q1Output 13Q0Output 04Q2Output 25Q6Output 66Q7Output 77Q3Output 38GND (VSS)Ground9Q8Output 810Q4Output 411Q9Output 912Carry OutUsed for cascading counters13Clock EnableDisables counting when HIGH14ClockTrigger input for counting pulses15ResetResets count to Q016VDDPositive Supply VoltageProduct SpecificationsParameterValueIC FunctionDecade Counter/DividerLogic FamilyCMOSPackage TypeDIP-16Supply Voltage Range3V – 15V         ‘Max Clock Frequency5 MHz (typical)Input TypeCMOS LogicOutput Type10 decoded digital outputsOperating Temperature-55°C to 125°CApplicationsLED chasers and flashersEvent countersFrequency dividersTiming sequencesLight pattern generatorsDigital clocksSignal sequencing for robotics
