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 Name | Description |
|---|---|---|
| 1 | Clock (CLK) | Input clock signal to increment the count |
| 2 | Clock Inhibit (CI) | Disables counting when HIGH |
| 3 | Display Enable (DE) | Enables or disables the 7-segment display |
| 4 | Display Enable Output (DEO) | Output for enabling cascaded displays |
| 5 | Carry Out (CO) | Carry-out signal for cascading multiple ICs |
| 6 | Segment F Output (F) | Drives segment ‘F’ of 7-segment display |
| 7 | Segment G Output (G) | Drives segment ‘G’ of 7-segment display |
| 8 | Ground (GND) | Power ground |
| 9 | Segment B Output (B) | Drives segment ‘B’ of 7-segment display |
| 10 | Segment A Output (A) | Drives segment ‘A’ of 7-segment display |
| 11 | Segment C Output (C) | Drives segment ‘C’ of 7-segment display |
| 12 | Segment D Output (D) | Drives segment ‘D’ of 7-segment display |
| 13 | Segment E Output (E) | Drives segment ‘E’ of 7-segment display |
| 14 | Segment DP Output (DP) | Drives decimal point (DP) of display |
| 15 | Reset (RST) | Resets count to 0 when HIGH |
| 16 | VCC | Power 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.
