Product Introduction

Overview

The THVD1552DGS is a part of the THVD15xx family of noise-immune RS-485/RS-422 transceivers designed by Texas Instruments. These devices are engineered to operate in rugged industrial environments, offering robust protection against high levels of IEC electrical fast transients (EFT) and IEC electrostatic discharge (ESD) events. This eliminates the need for additional system-level protection components. The THVD1552DGS operates from a single 5-V supply and features an extended common-mode voltage range, making it suitable for multi-point applications over long cable runs. It is available in small VSSOP packages, ideal for space-constrained applications, and is characterized over ambient free-air temperatures from –40°C to 125°C.
