XL485-SS – RS-485 / RS-422 Transceiver – Xinluda

About this part

The XL485-SS from Xinluda is a +5V, half-duplex RS-485/RS-422 transceiver designed for robust differential data transmission over industrial twisted-pair buses. The device integrates one driver and one receiver and supports data rates up to 10Mbps, making it a versatile choice for high-speed multipoint communication links. Onboard fail-safe circuitry guarantees a defined logic-high receiver output when the inputs are open or shorted, improving reliability in noisy field-wiring environments.

With a receiver input impedance of 1/8 unit load, the XL485-SS allows up to 256 transceivers to share a single bus, supporting large multidrop networks. Separate driver-enable (DE) and receiver-enable (RE) pins place the driver and receiver outputs into a high-impedance tri-state when disabled, simplifying bus arbitration. The device is rated for ±15kV Human Body Model (HBM) ESD on the A/B bus pins and operates across the full -40°C to +85°C industrial temperature range.
