THVD15xx is a family of noise-immune RS-485/RS-422 transceivers designed to operate inrugged industrial environments. The bus pins of these devices are robust to high levels of IECelectrical fast transients (EFT) and IEC electrostatic discharge (ESD) events, eliminating the needfor additional system-level protection components.
Each of these devices operates from a single 5-V supply. The devices in this familyfeature an extended common-mode voltage range which makes them suitable for multi-pointapplications over long cable runs.
THVD15xx family of devices is available in small VSSOP packages for space-constrainedapplications. These devices are characterized over ambient free-air temperatures from –40°C to125°C.
