This 14-pin logic chip can be configured to count from 0 to 9 with binary-coded decimal (BCD) outputs. Separate divide-by-2 and divide-by-5 sections provide flexible counting options, while reset-to-zero and set-to-nine inputs simplify circuit control. Operating from a 5V supply (4.75–5.25V), it is a practical choice for pulse counters, digital clock circuits, educational experiments, and DIY electronics projects.\u003c\/p\u003e","brand":"SciencePurchase","offers":[{"title":"Default Title","offer_id":67648677871853,"sku":"1074LS90","price":1.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/9136\/6829\/files\/871ba846b6a7.png?v=1791218112","url":"https:\/\/www.sciencepurchase.com\/products\/ic-logic-decade-counter","provider":"SciencePurchase","version":"1.0","type":"link"}
