XD485 – RS-485/RS-422 Transceiver – Xinluda

The Xinluda XD485 is a +5V, half-duplex RS-485/RS-422 transceiver in a through-hole DIP-8 package, integrating one driver and one receiver with separate enable controls. It is the DIP-8 member of the XL485CS transceiver family.

The Xinluda XD485 is a single +5V, half-duplex RS-485/RS-422 transceiver supplied in a through-hole DIP-8 (PDIP-8) package. It integrates one driver and one receiver with separate driver-enable (DE) and receiver-enable (RE) controls; the driver and receiver outputs are high-impedance (tri-state) when disabled, so multiple nodes can share a common two-wire bus. The XD485 is the DIP-8 member of the Xinluda XL485 family (which also includes the XL485CS in SOP-8 and the XL485-SS in MSOP-8) and uses the standard single-driver/single-receiver +5V RS-485 pinout, making it a convenient option for industrial communication boards.

Key Features

• Half-duplex RS-485 / RS-422 transceiver: one driver, one receiver
• Single +5V supply operation (4.5V to 5.5V)
• Separate driver-enable (DE) and receiver-enable (RE) pins with high-impedance (tri-state) outputs when disabled
• Fail-safe receiver design ensures a defined output state when the receiver inputs are open or shorted
• 1/8 unit-load receiver input impedance, allowing up to 256 transceivers on a single bus
• ±15kV Human Body Model (HBM) ESD protection on the A/B bus pins
• Data rate up to 10 Mbps
• Operating temperature range -40°C to +85°C
• Through-hole DIP-8 (PDIP-8) package for sockets, prototyping and field-serviceable assemblies

Applications

• Industrial automation and PLC communication links
• RS-485 / RS-422 multidrop data networks
• Building automation, HVAC and lighting control buses
• Metering, energy monitoring and SCADA nodes
• Motor drives and factory-floor equipment interfaces
• Standard +5V DIP-8 RS-485 board designs

Why Source XD485 from Pacific Component Xchange

The XD485 is a hard-to-find part with little to no authorized-distributor inventory, so spot availability and pricing move quickly. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs, interface ICs and optocouplers. We help engineers and buyers secure XD485 and equivalent RS-485 transceivers when standard channels show zero stock.
