XL3485 – RS-485/RS-422 Transceiver – Xinluda

The Xinluda XL3485 is a 3.3V low-power half-duplex RS-485/RS-422 transceiver with one driver and one receiver in an SOP-8 package, featuring thermal shutdown, current limiting, and a fail-safe receiver.

The XL3485 from Xinluda is a 3.3V low-power half-duplex transceiver designed for RS-485 and RS-422 balanced serial communication. Integrating one differential driver and one differential receiver, it operates from a single 3.3V supply with no external charge pump required, making it well suited to industrial networking, building automation, and field-bus applications where robust differential signaling is needed over long distances.

The XL3485 is interoperable with +5V logic, supports a wide common-mode input voltage range, and is housed in a compact SOP-8 package. Built-in protection features include short-circuit current limiting, over-temperature (thermal) shutdown, and a receiver fail-safe that guarantees a logic-high output when the inputs are open or undriven.
