Overview
The THVD2410DGKR is a ±70-V fault-protected, half-duplex RS-485 transceiver manufactured by Texas Instruments. This device operates on a single 3-V to 5.5-V supply and is designed to meet or exceed the requirements of the TIA/EIA-485A and TIA/EIA-422B standards. It features integrated IEC ESD protection, eliminating the need for external system-level protection components. The THVD2410 is particularly suited for rugged industrial environments, offering robust communication over extended cable run lengths and in the presence of large ground loop voltages.
