Overview
The THVD1510DR is a member of the THVD15xx family of noise-immune RS-485/RS-422 transceivers designed by Texas Instruments. These devices are engineered to operate in rugged industrial environments, offering robust protection against high levels of IEC electrical fast transients (EFT) and IEC electrostatic discharge (ESD) events. This eliminates the need for additional system-level protection components. The THVD1510DR operates from a single 5-V supply and features an extended common-mode voltage range, making it suitable for multi-point applications over long cable runs. It is available in both SOIC and VSSOP packages, catering to various application needs including space-constrained designs.
