Texas Instruments THVD15xx RS-485/RS-422 Transceivers
Texas Instruments THVD15xx RS-485/RS-422 Transceivers are noise-immune and are designed to operate in rugged industrial environments. The bus pins of these devices are robust to high levels of IEC Electrical Fast Transients (EFT) and IEC ElectroStatic Discharge (ESD) events, eliminating the need for additional system-level protection components. Each of the THVD15xx devices operates from a single 5V supply. These devices feature an extended common-mode voltage range which makes them suitable for multi-point applications over long cable runs.
