The CD4017 IC is a decade counter that counts to ten. It has 10 outputs that represent the numbers 0 to 9. The counter increases with one for every rising clock pulse. After the counter has reached 9, it starts again from 0 with the next clock pulse. This is a great chip for making running LEDs! See a circuit example further down.

2023年12月15日 · A CMOS decade counter like 4017 IC, incorporates a 5-stage Johnson counter alongside 10 decoded outputs to enable counting up to 10 decimal values. With 16 pins in total, this IC dedicates 10 and 16 pins to serve as output pins, each with its specific functionality, outlined as follows:

Divide-by-8 Counter/Divider with 8 Decoded Outputs. Texas Instruments (TI) is a publicly traded company that designs and manufactures semiconductor and computer technology products. It was founded in 1930 and is headquartered in Dallas, Texas.

The company was known for its innovation in the development of the first commercial transistor and for its contributions to the advancement of the integrated circuit technology. Fairchild became a leading supplier of power semiconductors, analog and mixed-signal integrated circuits, and other semiconductor products.

The ’HC4017 is a high speed silicon gate CMOS 5-stage Johnson counter with 10 decoded outputs. Each of the decoded outputs is normally low and sequentially goes high on the low to high transition clock period of the 10 clock period cycle.

Let us now introduce you to a new IC named IC 4017. It is a CMOS decade counter cum decoder circuit that can work out of the box for most of our low-range counting applications. It can count from zero to ten and its outputs are decoded.

The IC CD4017 is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using Carry pin.
