Commonly known as the 7490 IC, it is a 4-bit asynchronous (ripple) counter capable of counting from 0 to 9 (BCD) and automatically resetting to zero after the tenth count. The IC is widely used wherever reliable decimal counting and frequency division are required.\u003c\/p\u003e\n\u003cp\u003eThe 74LS90 consists of two internal counter sections: a divide-by-2 stage and a divide-by-5 stage. These sections can be connected together to form a divide-by-10 (decade) counter or configured independently to create various counting sequences such as BCD (Binary Coded Decimal), Modulo-2, Modulo-5, Modulo-6, Modulo-10, Modulo-12, and other custom counting circuits. This flexibility makes the IC suitable for a wide range of digital counting applications.\u003c\/p\u003e\n\u003cp\u003eBuilt using Low-Power Schottky TTL (LS TTL) technology, the 74LS90 provides fast switching performance, low power consumption, and compatibility with standard TTL logic families. It operates from a standard 5V power supply and is available in a 14-pin DIP package, making it easy to use in breadboards, PCBs, and educational development projects.\u003c\/p\u003e\n\u003cp\u003eThe 74LS90 is commonly used in digital clocks, event counters, frequency divider circuits, timer systems, digital instruments, embedded systems, industrial automation, and educational electronics where accurate counting and frequency division are required.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e4-bit asynchronous decade (BCD) counter.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCounts from 0 to 9 (Modulo-10).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInternal divide-by-2 and divide-by-5 counter sections.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConfigurable for Modulo-2, Modulo-5, Modulo-6, Modulo-10, Modulo-12, and custom counting sequences.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHigh-speed Low-Power Schottky TTL (LS TTL) technology.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eStandard 5V operating voltage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFast switching performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLow power consumption.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTTL compatible.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eReset inputs for flexible counter configuration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAvailable in a 14-pin DIP package.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEasy integration into digital logic circuits.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eDigital clocks\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFrequency divider circuits\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEvent counters\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTimer circuits\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePulse counting systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBCD counting applications\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDigital instrumentation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIndustrial automation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEmbedded systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRobotics projects\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eElectronic measurement equipment\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEducational and laboratory projects\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"electro robo store","offers":[{"title":"Default Title","offer_id":52754466210068,"sku":"MT0726","price":35.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/6590\/0052\/files\/1_68df98a4-7374-4072-9a74-667b2cf2a5e6.avif?v=1783323090","url":"https:\/\/electro-robo.com\/products\/74ls90-decade-counter-ic-7490-ic-dip-14-package","provider":"Electro Robo Store","version":"1.0","type":"link"}
