XL3085 – RS-485/RS-422 Transceiver – Xinluda

The Xinluda XL3085 is a +5V, half-duplex RS-485/RS-422 transceiver with one driver and one receiver, ±15kV HBM ESD protection, and fail-safe receiver inputs in an SOP-8 or DIP-8 package.

The XL3085 from Xinluda is a +5V, half-duplex RS-485/RS-422 transceiver designed for robust, error-free data communication over multipoint serial buses. It integrates a single driver and a single receiver, with driver-enable (DE) and receiver-enable control that place the driver and receiver outputs into a high-impedance (tri-state) condition when disabled. Slew-rate (swing-rate) limiting helps suppress reflections and EMI, supporting reliable transmission across long cable runs in noisy industrial environments.

Built-in fail-safe circuitry guarantees a known, correct receiver output state when the receiver inputs are left open or shorted, eliminating spurious data on idle or fault conditions. With a receiver input impedance of one-eighth (1/8) unit load, the XL3085 allows as many as 256 transceivers to share a single bus, making it well suited to large multidrop networks. The device carries ±15kV Human Body Model (HBM) ESD protection on its bus pins for added field reliability, and it complies with the Q/GDW 11179.11-2015 specification for energy-meter components.
