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.

• Built-in 7-segment decoder and display driver
• 4-bit binary ripple counter
• Direct interface with common-cathode 7-segment displays
• Wide supply voltage range: 3V to 15V
• Low power consumption
• High noise immunity

Technical Specifications:
