It goes high when the counter reads 6 counts. It goes high when the counter reads 2 counts. It goes high when the counter reads 0 counts. It goes high when the counter reads 5 counts. It has 16 pins and the functionality of each pin is explained as follows: The ic 4017 internal structure is shown below. ![]() Now the condition remains until another positive edge of the next cycle arrives, after that the o/p moves to pin1 or output 5 and maintains this condition. If two cycles of the square wave are applied toward the clock input, then the output will shift to output 4 on the positive edge of the primary cycle which alters output-4 to high state & output-3 to low state. On each count among 0 to 9, the particular output pin can include a high state & the remaining output maintains low simply one o/p will be high at a time.įor instance, if the count is presently three then the output at pin-7 is will be in a high state whereas the remaining pins are in a less state. Once it reaches then the output will count at ‘9’ and again it repeats from 0 & continues this revolution similar to a ring counter. Here, the output begins from ‘0’ and moves to output ‘9. ![]() This IC counts for every positive otherwise increasing edge input provided at the CLK input. This IC includes 16-pins where 10 & 16 pins are output pins. This IC can be used in different counter circuits such as an LED chaser light & also a non-contact circuit with an AC detector. 4017 IC Pin Configuration of IC 4017Ī CMOS decade counter like 4017 IC includes a five-stage Johnson counter & 10 decoded outputs for counting up to 10 decimals. This IC includes the counter as well as the decoder. So it is one of the most flexible counters because it counts up to 10 & also it includes 10 separate outputs. This CMOS IC is frequently used in designing the 10 LEDs-based circuits to run the light for beginners. This decade counter is similar to Johnson 10 stage decade counter. This IC will count from 0 to 10 and the circuit with an IC 4017 will save board space as well as the time necessary to design the circuit. The CD4017 IC is a CMOS Decade counter and it is used in the applications of low-range counting. ![]()
