{"product_id":"sn74ahc126ns","title":"SN74AHC126NS","description":"\u003cp\u003eThe SN74AHC126NS is a high-speed quad non-inverting buffer from Texas Instruments, part of the 74AHC logic family. It features four independent buffer channels with 3-state outputs, allowing for efficient bus-oriented applications. Operating across a wide voltage range of 2V to 5.5V, it provides compatibility with both 3.3V and 5V logic systems. Each output can source or sink 8mA, making it suitable for driving moderate loads. Housed in a compact 14-pin SOIC package, this buffer is ideal for signal conditioning, bus isolation, and level-shifting tasks in a variety of digital systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWide 2V to 5.5V Supply Range: Ensures compatibility with both 3.3V and 5V logic systems, simplifying mixed-voltage designs.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Allows multiple devices to share a common bus without contention, enhancing system flexibility.\u003c\/li\u003e\n\u003cli\u003eHigh Output Drive (8mA): Capable of driving multiple loads or LEDs directly, reducing the need for external drivers.\u003c\/li\u003e\n\u003cli\u003eHigh-Speed CMOS Technology: Provides fast propagation delays while maintaining low power consumption.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBus Interfacing and Isolation\u003c\/h3\u003e\u003cp\u003eThe 3-state outputs allow the SN74AHC126NS to be used for connecting multiple peripherals to a shared data bus. When the output enable is deasserted, the buffer enters a high-impedance state, preventing bus contention.\u003c\/p\u003e\u003ch3\u003eSignal Buffering for High-Fanout Applications\u003c\/h3\u003e\u003cp\u003eWith its 8mA source and sink capability, this buffer can drive multiple loads, ensuring signal integrity in systems where a single logic gate output must drive several inputs.\u003c\/p\u003e\u003ch3\u003eLevel Shifting Between 3.3V and 5V Systems\u003c\/h3\u003e\u003cp\u003eOperating from 2V to 5.5V, the SN74AHC126NS can be powered from a 3.3V rail to interface with 5V logic, or vice versa, providing a simple level-shifting solution.\u003c\/p\u003e\u003ch3\u003eDriving LEDs and Low-Power Loads\u003c\/h3\u003e\u003cp\u003eThe 8mA output current is sufficient to directly drive standard LEDs with a current-limiting resistor, simplifying control circuits in indicator panels.\u003c\/p\u003e\u003ch3\u003eIndustrial Control Logic\u003c\/h3\u003e\u003cp\u003eIts wide operating temperature range (-40°C to 85°C) and robust CMOS technology make it suitable for industrial control systems, PLCs, and sensor interfaces.\u003c\/p\u003e\u003ch3\u003eMemory Address Decoding\u003c\/h3\u003e\u003cp\u003eUsed as a buffer for address lines, it isolates the memory controller from the capacitive load of multiple memory chips, improving signal timing and reliability.\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\u003eTexas Instruments\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProduct Series\u003c\/td\u003e \t\u003ctd\u003e74AHC\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, Non-Inverting\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Elements\u003c\/td\u003e \t\u003ctd\u003e4\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Bits per Element\u003c\/td\u003e \t\u003ctd\u003e1\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 - Output High, Low\u003c\/td\u003e \t\u003ctd\u003e8mA, 8mA\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eVoltage - Supply\u003c\/td\u003e \t\u003ctd\u003e2V ~ 5.5V\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eOperating Temperature\u003c\/td\u003e \t\u003ctd\u003e-40°C ~ 85°C (TA)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eGrade\u003c\/td\u003e \t\u003ctd\u003e-\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eQualification\u003c\/td\u003e \t\u003ctd\u003e-\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eMounting Type\u003c\/td\u003e \t\u003ctd\u003eSurface Mount\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePackage \/ Case\u003c\/td\u003e \t\u003ctd\u003e14-SOIC (0.209\", 5.30mm Width)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eSupplier Device Package\u003c\/td\u003e \t\u003ctd\u003e14-SO\u003c\/td\u003e \u003c\/tr\u003e  \u003c\/tbody\u003e\n\u003c\/table\u003e\u003cdl\u003e\n\u003cdt\u003eQ: What is the logic family of the SN74AHC126NS?\u003c\/dt\u003e\n\u003cdd\u003eA: It belongs to the 74AHC (Advanced High-Speed CMOS) logic family.\u003c\/dd\u003e\n\u003cdt\u003eQ: What is the function of this IC?\u003c\/dt\u003e\n\u003cdd\u003eA: It is a quad (4-channel) non-inverting buffer with 3-state outputs.\u003c\/dd\u003e\n\u003cdt\u003eQ: How many channels does it have?\u003c\/dt\u003e\n\u003cdd\u003eA: It has 4 independent buffer channels.\u003c\/dd\u003e\n\u003cdt\u003eQ: What is the output type?\u003c\/dt\u003e\n\u003cdd\u003eA: The outputs are 3-State, allowing for connection to shared buses.\u003c\/dd\u003e\n\u003cdt\u003eQ: What is the operating voltage range?\u003c\/dt\u003e\n\u003cdd\u003eA: It operates from 2V to 5.5V, making it suitable for both 3.3V and 5V systems.\u003c\/dd\u003e\n\u003cdt\u003eQ: What package is available?\u003c\/dt\u003e\n\u003cdd\u003eA: It comes in a 14-pin SOIC package (5.30mm width).\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Texas Instruments","offers":[{"title":"Default Title","offer_id":53665824244001,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/hqickey.com\/de\/products\/sn74ahc126ns","provider":"HQICKEY","version":"1.0","type":"link"}
