CD4026 Logic decimal count / crossover
The CD4026 is a CMOS integrated circuit primarily used for decimal counting and display driving applications. It includes a 7-segment decoder, display driver, and a 4-bit binary ripple counter. The CD4026 simplifies the process of driving 7-segment LED displays by converting binary-coded decimal (BCD) inputs into the necessary signals for each segment of the display.
