{"product_id":"mm74hc240sjx","title":"MM74HC240SJX","description":"\u003cp\u003eThe MM74HC240SJX from Fairchild Semiconductor is a dual-channel inverting buffer from the 74HC logic family. It operates from 2V to 6V, providing compatibility with 5V systems. The 3-state outputs allow the device to be disconnected from the bus, enabling shared lines. It delivers 7.8mA drive current, suitable for driving LEDs or logic inputs. Housed in a 20-SOIC package, it is ideal for space-conscious designs. Typical applications include memory address buffering, signal inversion, and industrial control where active-low signals are required.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDual Channels: Two independent inverting buffers in one package, saving board space.\u003c\/li\u003e\n\u003cli\u003eInverting Function: Useful for active-low logic and complement signal generation.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Allows bus sharing and output isolation.\u003c\/li\u003e\n\u003cli\u003eWide Voltage Range (2V-6V): Works with 5V and 3.3V systems.\u003c\/li\u003e\n\u003cli\u003eStandard 20-SOIC Package: Easy to manufacture and widely available.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInverting Bus Drivers for Memory Systems\u003c\/h3\u003e\u003cp\u003eThe inverting function is useful for active-low control signals, buffering address lines in SRAM interfacing.\u003c\/p\u003e\u003ch3\u003eLED Display Multiplexing\u003c\/h3\u003e\u003cp\u003eDual inverting buffers with 3-state control drive common-anode LED displays, reducing component count.\u003c\/p\u003e\u003ch3\u003eIndustrial Sensor Signal Inversion\u003c\/h3\u003e\u003cp\u003eInverts sensor outputs (e.g., active-low limit switches) to match PLC input logic levels.\u003c\/p\u003e\u003ch3\u003e5V to 3.3V Level Shifting with Inversion\u003c\/h3\u003e\u003cp\u003eOperates at 5V, but with 3-state, can be used in mixed-voltage systems where inversion is needed.\u003c\/p\u003e\u003ch3\u003eClock Inversion for Differential Signaling\u003c\/h3\u003e\u003cp\u003eProvides complementary clock signals for systems requiring inverted clock phases.\u003c\/p\u003e\u003ch3\u003eAutomotive Lighting Control\u003c\/h3\u003e\u003cp\u003eBuffers and inverts PWM signals for LED dimming in automotive interior lighting, with 3-state for fault isolation.\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\u003e74HC\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 -
