Overview
The THVD1510D is a part of the THVD15xx family of 5-V RS-485/RS-422 transceivers designed by Texas Instruments. These devices are engineered to operate in rugged industrial environments, offering robust protection against electrostatic discharges (ESD) and electrical fast transients (EFT). The THVD1510D 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.
