Overview
The THVD2410DRBR, produced by Texas Instruments, is a ±70-V fault-protected, half-duplex RS-485 transceiver. 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 is particularly suited for rugged industrial environments due to its robust bus interface protection and integrated IEC ESD protection. The THVD2410 supports data transmission up to 500 kbps and features active-high driver enables and active-low receiver enables, making it versatile for various industrial applications.
