IC 4026 – 7-Segment Display Driver with Counter (Pack of 2)

Introduction

The IC 4026 is a decade counter with an integrated 7-segment display driver, commonly used in digital counting and display applications. It eliminates the need for a separate BCD to 7-segment decoder, making it a preferred choice for numerical display circuits. This IC can count from 0 to 9 and directly drive common cathode 7-segment displays.


Pinout and Pin Configuration

Pin No.Pin NameDescription
1Clock (CLK)Input clock signal to increment the count
2Clock Inhibit (CI)Disables counting when HIGH
3Display Enable (DE)Enables or disables the 7-segment display
4Display Enable Output (DEO)Output for enabling cascaded displays
5Carry Out (CO)Carry-out signal for cascading multiple ICs
6Segment F Output (F)Drives segment ‘F’ of 7-segment display
7Segment G Output (G)Drives segment ‘G’ of 7-segment display
8Ground (GND)Power ground
9Segment B Output (B)Drives segment ‘B’ of 7-segment display
10Segment A Output (A)Drives segment ‘A’ of 7-segment display
11Segment C Output (C)Drives segment ‘C’ of 7-segment display
12Segment D Output (D)Drives segment ‘D’ of 7-segment display
13Segment E Output (E)Drives segment ‘E’ of 7-segment display
14Segment DP Output (DP)Drives decimal point (DP) of display
15Reset (RST)Resets count to 0 when HIGH
16VCCPower supply (3V – 15V)

Working Principle

The IC 4026 receives clock pulses (Pin 1) to increment the count. The internal decade counter converts this into a 7-segment output, driving segments A to G. The count can be reset using the Reset pin (Pin 15), and the Display Enable (Pin 3) controls whether the output is active. The Carry-Out (Pin 5) is used for cascading multiple counters.


Features and Specifications

  • Voltage Range: 3V – 15V
  • Counts from 0 to 9 with 7-segment output
  • Direct Display Driving (no need for external BCD decoder)
  • Clock Inhibit Pin for Control Applications
  • Reset and Carry-Out Functionality for expanded counting

Applications

  • Digital Counters and Event Counters
  • Timer Circuits
  • Scoreboards and Frequency Counters
  • Industrial Measurement Systems
  • Clock and Stopwatch Displays

Conclusion

The IC 4026 is a versatile and easy-to-use counter for 7-segment numerical displays, making it a great choice for digital clocks, event counters, and scoreboards. Its compact design and built-in decoder reduce circuit complexity, making it ideal for various electronic projects.
