The XD3485 from Xinluda is a low-power, half-duplex RS-485 transceiver designed for robust differential data communication in electrically noisy environments. Operating from a single 3.3V supply (and interoperable with +5V logic), the XD3485 integrates one driver and one receiver and is rated for data rates up to 12Mbps, making it suitable for high-speed industrial bus links. Its 1/8-unit-load receiver input allows up to 256 transceivers to share a single RS-485 bus. The XD3485 is offered in a through-hole DIP-8 package; the pin-compatible XL3485 provides the same function in an SOP-8 surface-mount package.
The XD3485 is a specialized Xinluda interface IC with limited authorized-distributor availability, which can make it difficult to source through conventional channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete interface and power-management components. We help engineers and buyers secure the XD3485 and similar scarce parts with a focus on authenticity, traceability, and reliable global shipping.
Because this is a Request-For-Quote (RFQ) item, pricing and lead time are confirmed per order based on current supply. Submit an RFQ for the XD3485 today and our sourcing team will respond with availability, pricing, and delivery options for your required quantity.
The XD3485 is a 3.3V-powered, half-duplex RS-485 transceiver from Xinluda. It contains one driver and one receiver, supports data rates up to 12Mbps, and allows up to 256 nodes on a single RS-485 bus thanks to its 1/8 unit-load receiver input. It is supplied in a through-hole DIP-8 package.
The XD3485 and XL3485 are functionally the same 3.3V RS-485 transceiver and share the same datasheet. The primary difference is the package: the XD3485 is supplied in a through-hole DIP-8 package, while the XL3485 is supplied in a surface-mount SOP-8 package.
The XD3485 supports data rates up to 12Mbps and allows up to 256 transceivers (nodes) on the bus thanks to its 1/8 unit-load receiver input impedance.
The XD3485 includes driver short-circuit (current-limited) output protection, over-temperature thermal shutdown, and receiver open-circuit fail-safe protection (logic-high output when receiver inputs are open), plus a low-current shutdown mode for robust operation in noisy industrial environments.
Yes. The XD3485 is a hard-to-find part with limited authorized-distributor availability, and it is available through Pacific Component Xchange as a Request-For-Quote (RFQ) item. Submit an RFQ and our team will confirm pricing, lead time, and quantity availability.
The XD3485 operates over an industrial temperature range of -40u00b0C to +85u00b0C.
