THVD24x0 RS-422/RS-485 Transceivers

Texas Instruments THVD24x0 RS-422/RS-485 Transceivers are ±70V fault-protected, half-duplex transceivers operating on a single 3.0V to 5.5V 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 need for external system-level protection components. Extended ±25V input common-mode range guarantees reliable data communication over longer cable run lengths and/or in the presence of large ground loop voltages. Enhanced 250mV receiver hysteresis ensures high noise rejection. Also, the receiver fail-safe feature guarantees a logic high when the inputs are open or shorted together.
