CD4017 Decade Counter IC DIP-16 Package

It’s a CD4017 decade counter IC in a DIP package. It has a supply voltage range of 15v and it has high noise noise immunity. This decade counter IC is generally used in the automotive section, instrumentation, medical electronics, alarm systems, Industrial electronics, and remote metering.

The CD4017 is a versatile integrated circuit (IC) widely used as a decade counter or divider. It belongs to the CMOS 4000 series of digital logic ICs and is specifically designed to divide input clock signals by 10. Packaged in a DIP-16 (Dual In-line Package with 16 pins), the CD4017 offers ease of use and integration into various electronic circuits, making it a popular choice among hobbyists, students, and professionals alike.

At its core, the CD4017 consists of a 5-stage Johnson decade counter/divider with 10 decoded outputs and an additional output for carry/borrow functions. It operates on a wide voltage range, typically from 3 to 15 volts, making it compatible with both TTL and CMOS logic families, thus enhancing its versatility in digital circuit design.

One of the distinctive features of the CD4017 is its ability to sequentially output a high signal on one of its 10 output pins in response to each clock pulse applied to its clock input pin. This sequential operation allows it to function as a decade counter, producing a count from 0 to 9 as the clock signal is applied.

The CD4017 utilizes a clock input signal to advance through its 10 output states, with each clock pulse causing the next output pin to go high in sequence. This behavior makes it suitable for various applications requiring sequential control or timing, such as LED chasers, sequential LED displays, and digital timers.

Moreover, the CD4017 offers flexibility in its operation, as it features reset and enables inputs that allow users to control its counting sequence. The reset input allows the counter to be cleared to its initial state (0) manually or through an external signal, while the enable input permits the counter to be temporarily disabled, halting its counting sequence until re-enabled.

The CD4017 can be configured in various modes of operation to suit specific application requirements. For instance, by connecting the carry/borrow output to the clock input, multiple CD4017 ICs can be cascaded to create larger counting sequences or divide input clock signals by higher factors, enabling complex counting and sequencing functions.

Furthermore, the CD4017’s low power consumption and high noise immunity characteristics make it suitable for battery-operated or noise-sensitive applications where power efficiency and signal integrity are critical.

The CD4017 is housed in a DIP-16 package, which offers ease of handling, soldering, and compatibility with standard breadboard and PCB layouts. Its pinout layout follows industry-standard conventions, simplifying integration into circuit designs and ensuring compatibility with other components.

Additionally, the CD4017 is supported by comprehensive datasheets and application notes provided by its manufacturer and various electronics resources, making it accessible to engineers and hobbyists of all skill levels. These resources offer guidance on proper usage, application examples, and circuit design considerations, enabling users to harness the full potential of the CD4017 in their projects.

In conclusion, the CD4017 decade counter IC packaged in a DIP-16 format represents a fundamental building block in digital circuit design, offering precise and reliable counting and sequencing capabilities. Its versatility, ease of use, and compatibility with various logic families make it a staple component in countless electronic projects, ranging from simple LED displays to sophisticated control systems. Whether used in educational settings to teach digital logic concepts or integrated into complex electronic systems, the CD4017 continues to be a go-to choice for designers seeking reliable and flexible decade-counting solutions.
