3 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.
