Overview
The THVD1510DGK is a member of the THVD15xx family of RS-485/RS-422 transceivers produced by Texas Instruments. These devices are designed to operate in rugged industrial environments and are characterized by their robustness against high levels of electrical fast transients (EFT) and electrostatic discharge (ESD) events. The THVD1510DGK 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 a small VSSOP package, ideal for space-constrained applications, and is specified over an ambient free-air temperature range from –40°C to 125°C.
