The CD4026 is a CMOS-based 7-segment counter IC designed to drive a 7-segment display directly, making it an excellent choice for digital counting applications. It is commonly used in electronic projects such as digital clocks, event counters, frequency counters, and scoreboards. The IC integrates a decade counter, a 7-segment decoder, and a display driver, eliminating the need for additional interfacing components.
The IC operates in decade counter mode (0–9) and provides decoded outputs to drive common-cathode 7-segment displays. It includes features such as carry-out, clock enable, display enable, and reset functions, offering flexibility in multi-digit counting applications. With wide operating voltage support from 3V to 15V, it is compatible with TTL and CMOS logic families.
The CD4026 is housed in a DIP package, making it breadboard and PCB-friendly for prototyping and project development. Its low power consumption and high noise immunity make it highly reliable for both educational and industrial projects.
