Descriptions:

The MAX3485ESA+T is a 3.3V-powered, half-duplex RS-485/RS-422 transceiver optimized for high-speed communication. It features a slew-rate-limited driver to reduce EMI and minimize reflections in unterminated cables. The device includes fail-safe circuitry to ensure a logic-high receiver output when inputs are open or shorted.

Features:

  • 3.3V Operation
  • 10Mbps Data Rate
  • Slew-Rate Limited for Reduced EMI
  • Low-Power Shutdown Mode (0.1µA max)
  • Enhanced ESD Protection (±15kV HBM)
  • 1/8 Unit Load (Allows up to 256 Nodes on a Bus)
  • Thermal Shutdown Protection
  • Industrial Temperature Range (-40°C to +85°C)

This transceiver is commonly used in industrial control, building automation, and other applications requiring robust serial communication.
