{"product_id":"sn74ls240ml1","title":"SN74LS240ML1","description":"\u003cp\u003eThe SN74LS240ML1 from onsemi is a dual inverting buffer with 3-state outputs, part of the 74LS TTL family. It operates from 4.75V to 5.25V and can sink 24mA or source 15mA, making it suitable for driving moderate loads. This IC is designed for bus-oriented systems where signal inversion and high-impedance control are required. It is commonly found in legacy 5V digital systems, memory interfacing, and industrial control applications.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Sink Current (24mA):\u003c\/strong\u003e Can directly drive LEDs, relays, or other peripheral loads without additional transistors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-State Outputs:\u003c\/strong\u003e Enables bus sharing and prevents data collisions in multi-device systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInverting Function:\u003c\/strong\u003e Provides signal inversion where needed, reducing the need for external inverters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProven 74LS Technology:\u003c\/strong\u003e Reliable and well-understood logic family for 5V systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eLegacy TTL Bus Interfacing\u003c\/h3\u003e\u003cp\u003eIn systems with older TTL logic, the SN74LS240ML1 provides the necessary inverting buffer function with 3-state outputs for bus arbitration.\u003c\/p\u003e\u003ch3\u003eMemory Address Inversion\u003c\/h3\u003e\u003cp\u003eUse it to invert address lines when memory mapping requires active-low signals, ensuring correct chip selection.\u003c\/p\u003e\u003ch3\u003ePeripheral Driver\u003c\/h3\u003e\u003cp\u003eWith 24mA sink capability, it can directly drive LEDs, relays, or small motors through a transistor interface.\u003c\/p\u003e\u003ch3\u003eSignal Inversion in Control Logic\u003c\/h3\u003e\u003cp\u003eIn industrial control panels, this IC inverts sensor signals to match the logic polarity required by the controller.\u003c\/p\u003e\u003ch3\u003eTest and Measurement Equipment\u003c\/h3\u003e\u003cp\u003eBuffer and invert signals in bench-top instruments, providing a robust output stage for external connections.\u003c\/p\u003e\u003ch3\u003e5V Digital Systems\u003c\/h3\u003e\u003cp\u003eIdeal for pure 5V systems where low-power Schottky technology offers a proven, reliable solution.\u003c\/p\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\u003ccol\u003e\u003c\/colgroup\u003e \u003ctbody\u003e \u003ctr\u003e \t\u003ctd\u003eProduct attributes\u003c\/td\u003e \t\u003ctd\u003eProperty Value\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eManufacturer\u003c\/td\u003e \t\u003ctd\u003eonsemi\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProduct Series\u003c\/td\u003e \t\u003ctd\u003e74LS\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePackaging\u003c\/td\u003e \t\u003ctd\u003eBulk | \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePart Status\u003c\/td\u003e \t\u003ctd\u003eActive\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eLogic Type\u003c\/td\u003e \t\u003ctd\u003eBuffer, Inverting\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Elements\u003c\/td\u003e \t\u003ctd\u003e2\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Bits per Element\u003c\/td\u003e \t\u003ctd\u003e4\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eInput Type\u003c\/td\u003e \t\u003ctd\u003e-\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eOutput Type\u003c\/td\u003e \t\u003ctd\u003e3-State\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eCurrent -
