CD4026 7-segment Counter IC
The IC CD4026 is an IC which can perform the function of both a counter as well a 7-segment Driver. One single IC can be used to count form zero (0) to nine (9) directly on a Common Cathode type 7-segment display. The count can be increased by simply giving a high clock pulse; also more than one digit (0-9) can be created by cascading more than one CD4026 IC. So if you have a 7-segment (CC) display on which you have to display numbers that are being counted based on some condition then this IC will be a perfect choice.
Features:
- Counter for 7-Segment display
- Can drive a common cathode 7-Segment display directly
- Easy to interface with timer or micron rollers (TTL compatible)
- Can be easily cascaded with more IC to display higher range of number
- Maximum Clock Frequency: 6Mhz
- Available in 16-pin PDIP, GDIP, PDSO packages
CD4026 Pin Configuration
| Pin Number | Pin Name | Description |
| 1 | Clock (CLK) | The counting happens when this clock pulse goes high , this pin is normally connected to 555 timer or other uC to produce a pulse |
| 2 | Clock Inhibit (INH) | Connected to the Ground (low) of the circuit, to enable clock pin |
| 3 | Enable Input (DEI) | This pin is connect to +5V (high) to enable the output pins (Out A to Out G) |
| 4 | Enable Output (DEO) | This is an output which always stays high, this pin will be only if more than one CD4026 IC is used (cascaded) |
| 5 | Divide by 10 (CO) | This is the carry over output pin; it produces a pulse after counting till 9. This pin will be only if more than one CD4026 IC is used (cascaded) |
| 6,7,9,10,11,12,13 | Out A,B,C,D,E, F,G | These are the decoded output pins which should connected to 7-Segment display. |
| 8 | Ground | The ground pin should be connected to ground of circuit |
| 14 | Not 2 out (UCS) | This is Ungated C segment pin. This is an output pin which will be rarely used when division is required. |
| 15 | Reset | This input pin when made high (+5V) will reset the count to 0. |
| 16 | Vcc | This pin powers the IC, typically +5V is used. |
Applications
- Used in 7-segment counter projects
- Can be used to count people or objects crossing a point
- Has capability to display a wide range of numbers from 0 – 999
- Used in project where Microcontrollers should be avoided
