Overview
The THVD1410DGKR is a 3.3-V to 5-V RS-485 transceiver produced by Texas Instruments. It is part of the THVD14xx family, designed to operate in rugged industrial environments. This device is robust against high levels of IEC electrical fast transients (EFT) and IEC electrostatic discharge (ESD) events, eliminating the need for additional system-level protection components. The THVD1410DGKR operates from a single supply between 3 V and 5.5 V and features an extended common-mode voltage range, making it suitable for multi-point applications over long cable runs. It is available in a small VSSOP (DGK) package with 8 pins, which helps save board space in space-constrained applications.
