Interface

RS-485 & RS-422 transceivers

RS-485 and RS-422 transceivers with a high level of IEC ESD integration, noise immunity and smallest solution size

Explore our portfolio of the highest performance transceivers for RS-422 and RS-485 interfaces with reliable communication in noisy and harsh environments. We provide integrated solutions in industry-standard packages and smaller space-saving packages.

ESD-integrated transceivers

RS-485 transceivers with integrated ESD protection up to 30-kV IEC 61000-4-2 contact discharge protection and 30-kV HBM protection to reduce cost and board space by eliminating external protection

Fault-protected transceivers

RS-485 transceivers with high bus-fault protection on data pins and wide common-mode voltage that are designed to protect and perform in harsh industrial environments.

Surge-protected transceivers

RS-485 transceivers with a high level of integrated surge protection (IEC 61000-4-5) to reduce external protection components

Isolated transceivers

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