One single IC can  use to count form zero (0) to nine (9) directly on a Common Cathode type 7-segment display. The count can  increase by simply giving a high clock pulse; also more than one digit (0-9) can  create by cascading more than one \u003cstrong\u003eCD4026 IC\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eHow to use a CD4026 IC\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp style=\"font-weight: 400;\"\u003eThe IC can work from 3V to 15V, but normally power with +5V to the Vdd\/Vcc pin and the Ground\/Vss pin is connected to ground. We have 7 output pins naming from Out A to Out G which is directly connected to the 7-segment display. The clock inhibits pin (pin 2) is held low (ground\/0V) so that the clock signals can send to the IC also the Enable Input pin (pin 3) make high (+5V) so that the output pins (Out A to G) can active.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eThe 7-segment pins will increment the count by one number each time when the clock pin (pin 1) is made high. This clock source can either be obtained from a \u003ca href=\"https:\/\/components101.com\/555-timer-ic-pinout-datasheet\"\u003e555 IC\u003c\/a\u003e or any other digital IC which is TTL compatible. They simply have to generate a pulse of low voltage 0V and high voltage 5V. In the circuit below I have used a clock source of 1Hz to increment the count.\u003c\/p\u003e\n\u003ch4\u003eReset Pin\u003c\/h4\u003e\n\u003cp style=\"font-weight: 400;\"\u003eThe Reset pin (pin 15) is use to reset the count back to zero when made high. There are three other output pins (pin 5,4,14) which will  use only when the IC needs to be cascaded. The pin Carryover (CO – pin 5) will stay high by default, but when the count reaches “9” it will give a small pulse and count will continue from “0” again.  This small pulse can also use to drive the clock pin of a cascaded IC to display more than one digit. The Direct Enable output (DEO) pin will always stay high, to enable any cascaded IC, if available. The Ungated C segment pin (pin 14) is use for any division operation; this pin will stay high by default and will go low when the count reaches “2”.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003col style=\"font-weight: 400;\"\u003e\n\u003cli\u003eUse in 7-segment counter projects\u003c\/li\u003e\n\u003cli\u003eCan be used to count people or objects crossing a point\u003c\/li\u003e\n\u003cli\u003eHas the capability to display a wide range of numbers from 0 to 999\u003c\/li\u003e\n\u003cli\u003eUse in the project where Microcontrollers are to be avoided.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003e\u003cstrong\u003e2D Model of CD4026 (PDIP)\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ch2\u003e\u003cstrong\u003eData Sheet:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/CD4026_Datasheet.pdf?v=1789233107\"\u003eCD4026 Datasheet\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e1 X CD4026 4026 Johnson Decade Counter\u003c\/p\u003e","brand":"Electronics Hub","offers":[{"title":"Default Title","offer_id":54466794553657,"sku":"product-6230","price":99.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/images-17-4-1.jpg?v=1789233112","url":"https:\/\/electronicshub.pk\/products\/cd4026-4026-johnson-decade-counter","provider":"Electronics Hub","version":"1.0","type":"link"}
