Renesas has a rich interface history dating back to the 1970s. Renesas' interface devices can enhance serial ports with IEC 61000 enhanced ESD protection, overvoltage protected transceivers, high-speed transceivers, low voltage and low power, low cost transceivers, and multiprotocol configurations. Our RS-485, RS-422 and RS-232 isolated and non-isolated transceivers are used by the biggest names in industrial process control, including data communication for Industrial Internet of Things (IIoT) networks; telecommunications; and hundreds of different applications.
