3 Description

THVD14xx 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 supply

between 3 V and 5.5 V. The devices in this family

feature an extended common-mode voltage range

which makes them suitable for multi-point

applications over long cable runs.

THVD14xx family of devices is available in small

VSON and VSSOP packages for space constrained

applications. These devices are characterized over

ambient free-air temperatures from .40°C to 125°C.
