Key Features

  • Single RS-485/RS-422 line transceiver with 3 V to 3.6 V supply range and differential Schmitt trigger inputs for superior noise immunity
  • 1/8 unit load receiver input impedance enables up to 256 nodes on a single RS-485 bus network
  • 8-pin SOIC package with half-duplex operation simplifies PCB layout for industrial communication interfaces

Applications

The MAX3483AEASA+ is ideal for RS-485 multi-drop networks in industrial automation, building control systems, and SCADA applications where up to 256 nodes must share a single 2-wire differential bus. Its 3 V to 3.6 V supply range makes it compatible with 3.3 V microcontrollers and DSPs used in PLCs, motor controllers, and process sensors communicating over RS-485 at data rates up to 250 kbps.

Frequently Asked Questions

How many RS-485 bus nodes can the MAX3483AEASA+ support with its 1/8 unit load input?

The MAX3483AEASA+ has a 1/8 unit load receiver input impedance, which allows up to 256 nodes to be connected on a single RS-485 bus network. Standard unit load transceivers are limited to 32 nodes, so the 1/8 unit load design enables 8 times as many devices per bus in large industrial networks.

Can the MAX3483AEASA+ interface directly with 3.3 V microcontrollers without level-shifting circuitry?

Yes, the MAX3483AEASA+ is designed for a 3 V to 3.6 V supply voltage, making it directly compatible with 3.3 V microcontrollers, DSPs, and FPGAs without external level translators. This simplifies board design and reduces component count in RS-485 serial interface circuits using modern low-voltage MCUs.

What data rate does the MAX3483AEASA+ support and how does it compare to the MAX485 for long-distance RS-485 wiring?

The MAX3483AEASA+ supports data rates up to 250 kbps, which is suitable for RS-485 runs exceeding 1,200 meters using twisted-pair cable at that speed. The MAX485 also supports 2.5 Mbps for shorter runs but requires a 5 V supply, whereas the MAX3483AEASA+ is purpose-designed for 3.3 V systems needing moderate speed and long cable reach in industrial fieldbus installations.
