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

Description

THVD15xx is a family of noise-immune RS-485/RS-422 transceivers designed to operate in rugged industrial environments. The bus pins of these devices are robust to high levels of IEC electrical fast transients (EFT) and IEC electrostatic discharge (ESD) events, eliminating the need for additional system-level protection components.

Each of these devices operates from a single 5-V supply. The devices in this family feature an extended common-mode voltage range which makes them suitable for multi-point applications over long cable runs.

THVD15xx family of devices is available in small VSSOP packages for space-constrained applications. These devices are characterized over ambient free-air temperatures from –40°C to 125°C.
