{"product_id":"sn74als641ans","title":"SN74ALS641ANS","description":"\u003cp\u003eThe SN74ALS641ANS is a non-inverting transceiver from the 74ALS family, designed for 5V operation. It features open collector outputs with 24mA sink capability, making it ideal for wired-OR logic and level shifting. Available in a 20-SOIC package, it is a practical choice for industrial control, LED driving, and legacy bus interfacing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Collector Outputs:\u003c\/strong\u003e Enables wired-OR connections and simple level shifting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh 24mA Sink:\u003c\/strong\u003e Drives LEDs, relays, and multiple logic inputs directly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBidirectional Operation:\u003c\/strong\u003e Handles data flow in both directions, reducing parts count.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide 5V Supply:\u003c\/strong\u003e Compatible with standard TTL logic levels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e5V Wired-OR Bus\u003c\/h3\u003e\u003cp\u003eUse the SN74ALS641ANS to create a wired-OR bus for interrupt lines or status signals in 5V systems.\u003c\/p\u003e\u003ch3\u003eLevel Shifting to Lower Voltages\u003c\/h3\u003e\u003cp\u003eWith pull-ups to a lower voltage rail, the open collector output can shift 5V logic down to 3.3V or 2.5V.\u003c\/p\u003e\u003ch3\u003eLED and Relay Driving\u003c\/h3\u003e\u003cp\u003eThe 24mA sink capability allows direct driving of LEDs or small relays without additional transistors.\u003c\/p\u003e\u003ch3\u003eBidirectional Data Transfer\u003c\/h3\u003e\u003cp\u003eInterface two 5V buses bidirectionally, with direction controlled by the DIR pin.\u003c\/p\u003e\u003ch3\u003eIndustrial Sensor Readout\u003c\/h3\u003e\u003cp\u003eRead digital sensors in industrial environments, using open collector outputs to wire multiple sensors to one input.\u003c\/p\u003e\u003ch3\u003eLegacy System Interfacing\u003c\/h3\u003e\u003cp\u003eConnect legacy 5V peripherals to a modern system, using the transceiver for signal conditioning.\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\u003e74ALS\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\u003eTransceiver, Non-Inverting\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Elements\u003c\/td\u003e \t\u003ctd\u003e1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Bits per Element\u003c\/td\u003e \t\u003ctd\u003e8\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\u003eOpen Collector\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eCurrent -
