Voltage translators or level shifters are not a specific brand but a category of electronic components used to convert signals between different voltage levels in circuits. These devices are essential in industries such as automotive, consumer electronics, and industrial automation, where they ensure compatibility between systems operating at varying voltages. Major manufacturers producing these components include Texas Instruments (USA), NXP Semiconductors (Netherlands), and ON Semiconductor (USA). Their products range from bidirectional level shifters to unidirectional voltage translators, catering to applications like I2C, SPI, and GPIO interfaces. These components are widely available on industrial supply platforms like Radwell and Grainger.
