open-in-new Find other RS-485 & RS-422 transceivers

Description

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 need for external system-level protection components. Extended ±25-V input common-mode range guarantees reliable data communication over longer cable run lengths and/or in the presence of large ground loop voltages. Enhanced 250-mV receiver hysteresis ensures high noise rejection. In addition, the receiver fail-safe feature guarantees a logic high when the inputs are open or shorted together.

THVD24x0 devices are available in small VSSOP and VSON packages for space-constrained applications. These devices are characterized over ambient free-air temperatures from –40°C to 125°C.

Description
The RS-485 half-duplex evaluation module (EVM) helps designers evaluate device performance, supporting fast development and analysis of data-transmission systems using any of the SN65HVD1x, SN65HVD2x, SN65HVD7x, SN65HVD8x and SN65HVD96 half-duplex transceivers. The EVM board comes without the RS-485 (...)
Features

The EVM lets you quickly, easily and accurately evaluate TI's family of RS-485 products.

Hardware:
  • RS-485 half-duplex EVM PWB
  • Screw-type SMA jacks and Bergstik headers serve as the I/O connections
  • Banana jacks serve as the DC power input terminals
