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 freeair

temperatures from .40°C to 125°C.
