Digital multiplexers and encoders are not specific brands but key components in industrial automation and electronics, widely used by manufacturers globally. Companies like Texas Instruments (USA), Analog Devices (USA), and Broadcom (USA) produce these components, which are essential for data transmission, signal processing, and control systems in industries such as telecommunications, automotive, and manufacturing. Digital multiplexers combine multiple input signals into a single output, while encoders convert data into specific formats for efficient transmission. These products are available through industrial suppliers like Radwell and Grainger, catering to maintenance, repair, and operations (MRO) needs.
