{"product_id":"ic-logic-decade-counter-10-pack","title":"IC Logic - Decade Counter - 10 Pack","description":"Build digital counting and frequency-divider circuits with the 74LS90 Decade Counter IC. 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.","brand":"SciencePurchase","offers":[{"title":"Default Title","offer_id":67648757989613,"sku":"1074LS90PK10","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0571\/9136\/6829\/files\/1cc785995451.png?v=1791218857","url":"https:\/\/www.sciencepurchase.com\/products\/ic-logic-decade-counter-10-pack","provider":"SciencePurchase","version":"1.0","type":"link"}
