CD4026 4026 Johnson Decade Counter IC
Availability: In Stock
4026 IC is a 4000 series IC. This CD4026 IC is a CMOS seven-segment counter IC and can be operated at very low power. This 16 dip ic is a decade counter, counts in decimal digits (0-9). CD4026 decade counter ic is used to display numbers on seven segment displays and it increments the number by one when a clock pulse is applied to its PIN 1. Means more the clock pulse rate, faster the numbers change in 7 Segment Display.
Features Of CD4026 Decade Counter Divider IC DIP-16:
- Counter for 7-Segment display
- Can drive a common cathode 7-Segment display directly
- Easy to interface with a timer or micron rollers (TTL compatible)
- Can be easily cascaded with more IC to display the higher range of number
- Maximum Clock Frequency: 6Mhz
Pin Configuration CD4026 Decade Counter 7 Segment Decoder IC:
- Clock (CLK) (1): The counting happens when this clock pulse goes high, this pin is normally connected to 555 timer or other uC to produce a pulse
- Clock Inhibit (INH) (2): Connected to the Ground (low) of the circuit, to enable clock pin
- Enable Input (DEI) (3): This pin is connected to +5V (high) to enable the output pins (Out A to Out G)
- Enable Output (DEO) (4): This is an output which always stays high, this pin will be only if more than one CD4026 IC is used (cascaded)
- Divide by 10 (CO) (5): This is the carryover output pin; it produces a pulse after counting till 9. This pin will be only if more than one CD4026 IC is used (cascaded)
- Out A,B,C,D,E, F,G (6,7,8,9,10,11,12,13): These are the decoded output pins which should be connected to 7-Segment display.
- Ground: The ground pin should be connected to the ground of the circuit
- Not 2 out (UCS) (14): This is Ungated C segment pin. This is an output pin which will be rarely used when division is required.
- Reset (15): This input pin when made high (+5V) will reset the count to 0.
- Vcc (16): This pin powers the IC, typically +5V is used.
Applications Of CD4026 IC:
- Used in 7-segment counter projects
- Can be used to count people or objects crossing a point
- Has the capability to display a wide range of numbers from 0 - 999
- Used in the project where Microcontrollers should be avoided
