Direction-controlled voltage translators are a category of electronic components, not a specific brand, used for level shifting between different voltage domains in circuits. These devices are offered by various manufacturers globally, including Texas Instruments (USA), NXP Semiconductors (Netherlands), and Analog Devices (USA). They serve industries like industrial automation, automotive, and consumer electronics, ensuring signal integrity across voltage levels. Key products include bidirectional voltage translators, unidirectional level shifters, and auto-direction sensing translators, commonly found on platforms like Radwell and Grainger for industrial procurement.
