Overview
The THVD2410DR is a ±70-V fault-protected, half-duplex RS-485 transceiver produced 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 THVD2410DR is suitable for robust communication in rugged industrial environments, with extended ambient temperature range from -40°C to 125°C and an operational common-mode range of ±25 V.
