Working Principles

The CD4026BNSR is based on CMOS technology and operates as a synchronous decade counter. It counts from 0 to 9 and then resets to 0 automatically. The counter advances on each rising edge of the clock input (CLK) when the clock enable input (CE) is high. The reset input (RST) can be used to manually reset the counter to 0. The carry output (CARRY) provides a signal when the count reaches 9.

The CD4026BNSR also includes outputs for driving a 7-segment display directly. Each segment of the display is controlled by a separate output pin (a, b, c, etc.). By connecting the appropriate segments to the corresponding inputs (A, B, C, etc.), the desired number can be displayed.

Detailed Application Field Plans

The CD4026BNSR can be used in various digital counting applications, such as:

1. Digital clocks
2. Timers
3. Scoreboards
4. Frequency dividers
5. Industrial automation systems
6. Traffic light control systems
7. Electronic games
8. Counting and sorting machines
