The MxL83111 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).
Wide 3.3V to 5V supply ensures reliable operation under a wide range of applications and in systems where the power supply may drop below 4.5V.
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)
- Wide supply range from 3.0 to 5.5V
- Hot Swap glitch protection RE and DE
- Thermal shutdown protects against driver contention
- Slew limited 250kbps speed
