The video shows how to connect a seven-segment display using the CD4026 chip. How to eliminate contact bounce by connecting a single capacitor. A few words about CMOS logic, its features, and ways to improve its stability.
The CD4026 chip is a decimal counter with a seven-segment decoder; its closest domestic equivalents are the K176IE3 and K176IE4.
