{"product_id":"mc74hct240adt1r2","title":"MC74HCT240ADT1R2","description":"\u003cp\u003eThe MC74HCT240ADT1R2 is an octal inverting buffer\/line driver from onsemi's 74HCT family. It features eight inverting buffers arranged in two groups of four, each with independent 3-state output enable controls. Operating from 4.5V to 5.5V, it is fully TTL-compatible, making it a direct replacement for TTL buffers in legacy systems. Each output can drive up to 6mA, suitable for driving buses and multiple loads. The 3-state outputs allow for bus sharing and isolation. Housed in a compact 20-TSSOP package, it is ideal for bus interfacing, signal inversion, and level shifting in computer, industrial, and communication systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTTL-Compatible Inputs:\u003c\/strong\u003e Directly interfaces with 5V TTL logic, simplifying system integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOctal (8-Channel) Buffering:\u003c\/strong\u003e Provides eight inverting buffers in a single package, saving board space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-State Outputs:\u003c\/strong\u003e Enables bus sharing and prevents signal contention in multi-device systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact TSSOP Package:\u003c\/strong\u003e Ideal for space-constrained PCB designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Temperature Range (-55°C to 125°C):\u003c\/strong\u003e Suitable for automotive and industrial applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTTL-Compatible Bus Interfacing\u003c\/h3\u003e\u003cp\u003eThe 74HCT family is designed to be pin-compatible with TTL logic, making the MC74HCT240ADT1R2 an ideal drop-in replacement in legacy TTL systems while offering CMOS advantages.\u003c\/p\u003e\u003ch3\u003eInverting Line Driving\u003c\/h3\u003e\u003cp\u003eWith 8 inverting buffers, this IC can drive long transmission lines with inverted signals, providing the necessary drive strength and noise immunity for reliable communication.\u003c\/p\u003e\u003ch3\u003eMemory Address\/Data Buffering\u003c\/h3\u003e\u003cp\u003eIn microprocessor systems, this buffer can be used to isolate and drive address or data buses, with 3-state outputs preventing bus contention during memory access.\u003c\/p\u003e\u003ch3\u003eLevel Shifting from 5V to 3.3V\u003c\/h3\u003e\u003cp\u003eWhen powered at 5V, the inputs are TTL-compatible, allowing it to accept 3.3V logic signals and output 5V levels, useful for interfacing 3.3V microcontrollers with 5V peripherals.\u003c\/p\u003e\u003ch3\u003eIndustrial Control Signal Conditioning\u003c\/h3\u003e\u003cp\u003eIn industrial environments, this buffer can invert and condition control signals, providing clean, strong outputs for driving relays, solenoids, or other actuators.\u003c\/p\u003e\u003ch3\u003eHigh-Density PCB Design\u003c\/h3\u003e\u003cp\u003eThe compact TSSOP package saves board space, making it ideal for high-density designs where multiple buffer channels are needed in a small area.\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\u003e74HCT\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 -
