The MxL83102 is a half-duplex RS-485 transceiver specifically designed to support reliable communication in harsh industrial environments. The bus pins are designed to tolerate IEC electrical fast transients (EFT) and IEC electrostatic discharge (ESD).
The combination of integrated EFT and ESD protection, low slew limiting drivers, and extended operating conditions, ensures this family of products is well suited for a broad range of applications.
