The MxL83101 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).

Low power shutdown mode can extend the life of batteries in applications such as industrial notebooks, sensors, and solar powered applications, while hot swap ensures a deterministic logic state upon power-up.

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.

  • Advanced receiver-failsafe protection for open, shorted or terminated lines
  • Differential output exceeds 2.1V for PROFIBUS compatibility with a 5V supply
  • 1/8 unit load (256 bus nodes)
  • Single 5V supply
  • Hot Swap glitch protection RE and DE
  • Thermal shutdown protects against driver contention
  • Slew limited 250kbps speed
  • Small form factor NSOIC package
  • Extended temperature range from –40°C to 125°C
  • Low power shutdown mode (<1µA Typ)
  • Robust system protection
    • ±2kV EFT (IEC 61000-4-4)
    • ±8kV ESD Contact (IEC 61000-4-2)
