XD3485 – RS-485 Transceiver – Xinluda

The Xinluda XD3485 is a 3.3V-powered, half-duplex RS-485 transceiver rated for data rates up to 12Mbps with support for up to 256 nodes on the bus, supplied in a through-hole DIP-8 package.

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.

Key Features

• 3.3V single-supply operation (3.0V to 3.6V); interoperable with +5V logic
• Half-duplex RS-485 transceiver (one driver, one receiver)
• Data rates up to 12Mbps
• Up to 256 nodes on the bus (1/8 unit-load receiver input)
• -7V to +12V common-mode input voltage range
• Driver short-circuit (current-limited) output protection
• Over-temperature (thermal) shutdown protection
• Receiver open-circuit / fail-safe protection (logic-high output when inputs are open)
• Low-current shutdown mode
• High noise immunity for reliable transmission in noisy environments
• Operating temperature range: -40°C to +85°C
• DIP-8 through-hole package (XL3485 available in SOP-8)

Applications

• Industrial control and automation LANs
• Energy meters and metering equipment
• EMI-sensitive and electrically noisy environments
• Building automation and HVAC networks
• Multipoint RS-485/RS-422 data buses

Why Source XD3485 from Pacific Component Xchange
