Fail-safe biasing for ST485EB

Introduction
ST485EB is an RS-485 based interface designed for multipoint differential transmission on a
single twisted pair cable. It allows half duplex bi-directional transmission, long cable lengths
and high data rates.
Typical applications include LANs, industrial (PLC devices), automotive and computer
interfaces.
System evolution in the data communication field has lead to the development of faster
