Reliable, protected devices for long networks, high-data rates and noisy environments
3.3-V to 5-V transceivers optimized to meet the needs of cost-sensitive applications
Devices designed with ESD in mind: up to +30kV IEC 61000-4-2 contact discharge protection and greater than +30kV HBM protection
Rugged devices with high bus fault-protection and wide common-mode voltage, designed to perform in harsh industrial environments
Full-duplex and half-duplex isolated RS-485 transceivers with integrated capacitive isolation to provide 2.5-kVrms of isolation between the bus-line transceiver and the logic-level interface
Texas Instruments offers the most comprehensive RS-485 and RS-422 portfolio in the industry, meeting the RS-485 and RS-422 standards at 5V or 3.3V supply voltage and in half or full duplex modes. Whether designing for long networks or for high data rates, our RS-485 transceivers and RS-422 transceivers are reliable in high noise environments and give you the most robust IEC61000-4-2 ESD protection as well as IEC61000-4-4 EFT performance. The transceivers are ideal for many industrial applications, including motor drive and control, building and factory automation, metering and power infrastructure, and security systems.
