RS-485/RS-422 Overview

Reliable, protected devices for long networks, high data-rates & noisy environments

General-purpose transceivers

3.3-V to 5-V transceivers optimized to meet the needs of cost-sensitive applications

High-ESD transceivers

RS-485 transceivers designed with ESD in mind: up to +30kV IEC 61000-4-2 contact discharge protection and greater than +30kV HBM protection

Fault-protected transceivers

Rugged RS-485 transceivers with high bus fault-protection and wide common-mode voltage, designed to perform in harsh industrial environments

Isolated transceivers

Full-duplex and half-duplex isolated RS-485 transceivers with integrated capacitive isolation to provide 2.5-kVrms of isolation between the bus-line transceiver and the logic-level interface
