THVD2410 - Texas Instruments

THVD2410 3.3-V to 5-V RS-485 Transceivers

THVD2410 and THVD2450 are ±70-V fault-protected, half-duplex, RS-422/RS-485 transceivers operating on a single 3-V to 5.5-V supply. Bus interface pins are protected against overvoltage conditions during all modes of operation ensuring robust communication in rugged industrial environments. These devices feature integrated IEC ESD protection, eliminating the .
