{"product_id":"mm74hct240mtc","title":"MM74HCT240MTC","description":"\u003cp\u003eThe MM74HCT240MTC is a dual-channel inverting buffer from Fairchild Semiconductor, part of the 74HCT logic family. It operates at a supply voltage of 4.5V to 5.5V and provides 3-State outputs for bus-oriented applications. Each output can source or sink 7.2mA, making it suitable for driving moderate loads. The 20-TSSOP package is compact for space-constrained designs. Typical applications include bus interfacing, signal buffering, and level shifting in 5V digital systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTTL-Compatible Inputs: Directly interfaces with 5V TTL logic without additional circuitry, simplifying design.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Enables bus sharing and multiplexing, reducing the need for external isolation components.\u003c\/li\u003e\n\u003cli\u003eWide Temperature Range: Operates from -40°C to 85°C, suitable for industrial and automotive environments.\u003c\/li\u003e\n\u003cli\u003eCompact TSSOP Package: Saves board space in high-density designs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e5V Bus Interfacing\u003c\/h3\u003e\u003cp\u003eUse the MM74HCT240MTC to buffer and invert signals between 5V microcontrollers and peripheral devices, ensuring robust signal integrity on data buses.\u003c\/p\u003e\u003ch3\u003eMemory Address Driving\u003c\/h3\u003e\u003cp\u003eDrive high-capacitance memory address lines with the 3-State outputs, preventing signal degradation and allowing multiple memory banks to share the bus.\u003c\/p\u003e\u003ch3\u003eTTL-to-CMOS Level Shifting\u003c\/h3\u003e\u003cp\u003eWith TTL-compatible inputs, this buffer can interface TTL logic levels to CMOS devices operating at 5V, simplifying mixed-logic designs.\u003c\/p\u003e\u003ch3\u003eIndustrial Control Signal Buffering\u003c\/h3\u003e\u003cp\u003eIn industrial PLCs, buffer and invert control signals from sensors to logic controllers, providing isolation and driving capability for longer cable runs.\u003c\/p\u003e\u003ch3\u003eTest Equipment Channel Isolation\u003c\/h3\u003e\u003cp\u003eUse the 3-State feature to isolate multiple test channels, preventing back-drive and allowing safe multiplexing of measurement signals.\u003c\/p\u003e\u003ch3\u003eAutomotive ECU Signal Conditioning\u003c\/h3\u003e\u003cp\u003eBuffer and invert engine control signals in automotive ECUs, operating reliably across the -40°C to 85°C temperature range.\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\u003eFairchild Semiconductor\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 -
