XL3483 – RS-485/RS-422 Transceiver – Xinluda

The Xinluda XL3483 is a single 3.3V, slew-rate-limited, half-duplex true RS-485/RS-422 transceiver in an SOP-8 package, supporting up to 32 nodes on the bus.

The XL3483 from Xinluda is a single 3.3V-powered, half-duplex, true RS-485/RS-422 transceiver designed for robust differential data communication on long, electrically noisy bus networks. Built with slew-rate-limited drivers, the XL3483 minimizes electromagnetic interference (EMI) and suppresses the reflections caused by improperly terminated cables, enabling reliable, error-free data transmission. The device integrates one driver and one receiver and operates from a single 3.3V supply with no external charge pump, while remaining interoperable with +5V logic for easy integration into mixed-voltage systems.

Key Features

• True RS-485/RS-422 transceiver (one driver, one receiver, half-duplex)
• Single 3.3V supply operation – no charge pump required
• Slew-rate-limited driver for error-free data transmission at rates up to 250kbps
• -7V to +12V common-mode input voltage range
• Allows up to 32 transceivers on the bus
• Interoperable with +5V logic
• 2nA low-current shutdown mode
• Driver short-circuit current limiting with thermal shutdown that places driver outputs in a high-impedance state
• Receiver fault protection guarantees a logic-high output if both inputs are open circuit
• Space-saving SOP-8 package

Applications

• Industrial automation and process control networks
• RS-485/RS-422 multidrop bus systems
• Building automation, HVAC, and lighting control
• Smart metering and energy management
• Motor and motion control communication links
• Point-of-sale and embedded peripheral interfaces
