It counts down from a preset value and provides an output when it reaches zero. This IC is widely used in timers, frequency dividers, and other counting-related applications. The IC is available in an SMD package, making it ideal for compact and space-efficient designs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e8-Bit Synchronous Binary Down Counter: Provides an 8-bit counting capability with synchronous operation, meaning all bits are updated simultaneously with the clock signal.\u003c\/li\u003e\n\u003cli\u003eProgrammable Load Function: Allows the counter to be preset to any value, from which it will count down.\u003c\/li\u003e\n\u003cli\u003eZero Detection Output: Includes a terminal that goes low when the counter reaches zero, enabling it to signal the end of a counting sequence or trigger other events in the system.\u003c\/li\u003e\n\u003cli\u003eHigh-Speed Operation: Capable of operating at high speeds, making it suitable for fast counting applications.\u003c\/li\u003e\n\u003cli\u003eSynchronous Clear Function: Allows the counter to be reset synchronously with the clock signal.\u003c\/li\u003e\n\u003cli\u003eSMD Package: Available in various surface-mount packages, such as SOIC, TSSOP, etc., ideal for integration into high-density PCB designs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCounting Range: 8 bits (0 to 255)\u003c\/li\u003e\n\u003cli\u003eSupply Voltage: 2V to 6V\u003c\/li\u003e\n\u003cli\u003eInput Voltage: 0V to Vcc\u003c\/li\u003e\n\u003cli\u003eMaximum Clock Frequency: 30 MHz typical at Vcc = 5V\u003c\/li\u003e\n\u003cli\u003ePropagation Delay: 18 ns typical at Vcc = 5V\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40°C to +85°C\u003c\/li\u003e\n\u003cli\u003ePackage Type: SMD\u003c\/li\u003e\n\u003cli\u003ePin Count: 16\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Product images are for illustrative purposes only and may differ from the actual product.\u003c\/p\u003e\u003c!----\u003e","brand":"mysite","offers":[{"title":"Default Title","offer_id":46018891350187,"sku":"SMD-QC2319","price":0.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/1205\/1115\/files\/SOIC-16_SMD_Package_6a1f2dac-ee8b-4cea-a050-b2506659968d.jpg?v=1767603461","url":"https:\/\/www.yuzxcn.com\/products\/74hc40103-8-bit-synchronous-binary-down-counter-ic-smd-package","provider":"Yuzx","version":"1.0","type":"link"}
