Description: 1. The CD4026 is a decade counter/divider integrated circuit (IC) capable of counting from 0 to 9 or dividing by 10. It consists of four independent counters/dividers in a single package. 2. Features: Each counter/divider circuit includes a synchronous reset input, a carry-out output for cascading multiple chips, a decade mode (counting) or divide-by-ten mode (dividing), and an enable/disable input for controlling operation. 3. Applications: The CD4026 is commonly used in digital counters, timers, dividers, frequency dividers, and decoders. It finds applications in various sectors such as automotive, industrial control systems, telecommunications, consumer electronics, and more. 4. Flexibility: This IC can be operated both as a counter and divider by simply configuring the input mode through the enable/disable pin. In counting mode, it counts from 0 to 9 with each output representing a decimal digit. In dividing mode, it divides the input frequency by 10. 5. Ease of use: The CD402
