It is widely used in timing, counting, and digital display applications due to its flexible internal structure and reliable operation.\u003c\/p\u003e\n\u003cp\u003eThe IC consists of two internal counter sections: a divide-by-2 stage and a divide-by-5 stage. These sections can be combined to form a divide-by-10 (decade) counter, which counts from 0 to 9 in Binary Coded Decimal (BCD) format. By reconfiguring the internal connections, the 74LS90 can also be used to implement other counting modes such as bi-quinary, modulo-12, and modulo-16 counters, making it highly versatile for various digital design requirements.\u003c\/p\u003e\n\u003cp\u003eThe 74LS90 belongs to the Low Power Schottky TTL (LS TTL) family, offering fast switching speeds and low power consumption. It operates with a standard 5V power supply and is compatible with other TTL logic devices. Its asynchronous (ripple) counting design allows it to efficiently handle pulse counting and frequency division tasks.\u003c\/p\u003e\n\u003cp\u003eThis IC is commonly used in digital clocks, event counters, frequency dividers, timers, and display systems where accurate counting of pulses is required. Its reliability, flexibility, and ease of use make it a popular choice in both educational and industrial electronics.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e4-bit decade (BCD) counter IC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInternal divide-by-2 and divide-by-5 counter stages\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConfigurable for modulo-10, modulo-12, modulo-16, and other counters\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLow 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\u003eHigh-speed 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\u003eAsynchronous ripple counter design\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTTL compatible inputs and outputs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eReliable and stable operation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCompact 14-pin DIP package\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 and timers\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 and pulse counters\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDigital display systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIndustrial automation systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEmbedded electronics projects\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMeasurement instruments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSequence generation circuits\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEducational electronics experiments\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRobotics and control systems\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"electro robo store","offers":[{"title":"Default Title","offer_id":52755377127700,"sku":"MT0749","price":35.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/6590\/0052\/files\/ad.avif?v=1783331187","url":"https:\/\/electro-robo.com\/products\/74ls90-decade-counter-ic-7490-ic-dip-14-package-1","provider":"Electro Robo Store","version":"1.0","type":"link"}
