3 Description
THVD1419 and THVD1429 are half-duplex RS-485
transceivers with integrated surge protection. Surge
protection is achieved by integrating transient voltage
suppressor (TVS) diodes in the standard 8-pin SOIC
(D) package. This feature provides a substantial
increase in reliability for better immunity to noise
transients coupled to the data cable, eliminating the
need for external protection components.
Each of these devices operates from a single 3.3 V or
5 V supply. The devices in this family feature a wide
common-mode voltage range which makes them
suitable for multi-point applications over long cable
runs.
The THVD1419 and THVD1429 devices are available
in the industry standard SOIC package for easy drop-
in without any PCB changes. These devices are
characterized over ambient free-air temperatures
from –40°C to 125°C.
