Dld Projects Digital Clock Using 4026 Counter Ic Youtube Date: march 1, 2021main components:1. cd 4026be (6) the 4026 is a decade counter integrated circuit (ic) with decoded outputs for driving a common cathode s. All the circuit is power at 5v. note: the accuracy of this digital clock depends on how accurate you bring the ic 555 pulse to 1 hz. ic 4026 to 7 segment display connection: ic 4026 to 7 segment display connection. you need to connect the 220 ohm resistor to each segment as shown above.
Digital Pulse Counter Circuit Image below shows the pin layout of the ic: 4060 circuit (io1) divides crystal frequency 32 768 hz using a 14 stage binary prescaler down to 2 hz frequency. this 2hz frequency is fed to the clock pin 1 of the 4026 ic. the two switch are used to set the time and is achieved using 4060 pin by increasing the frequency that is being fed to 4026 ic. The 4026 is a cmos counter with integrated 7 segment display driver and is typically used in constructing a digital clock. each 4026 contains 4 logic gates, a counter and a 7 segment display driver that can drive an lcd or led display. it offers several advantages over other types of circuits since it’s simpler and more affordable than other. 24 hours digital clock using 4026 ic and 555 timer with 7 segment displays.like share and subscribedownload simulation file:for more details visit website:ht.

This circuit diagram is for a seven segment display driven by a 4026 decade counter, which receives the clock signal from a 555 timer ic. if you made the previous circuit to this, which used a push to make (ptm) switch to generate a clock pulse, then this circuit is a step forward and uses a 555 ic in astable mode to generate a slow clock pulse. At the end, we will see a practical example such as digital clock design. single digit counter example. this circuit can count from 0 9. because we use only one cd4026 ic and one seven segment display. the speed of counting display depends on the clock frequency. pin3 should remain active high. we can use pin15 to stop counter from working.
