Drivers

RS-485RS-422TransceiverIndustrial

The GB490H is a high-performance 3.3V/5V full-duplex RS-485/RS-422 transceiver, ideal for industrial networks requiring high node counts and robust ESD protection.

Best for

  • Industrial automation
  • Multi-node communication networks
  • High-speed data transmission

Avoid if

  • Applications requiring half-duplex only (though it can be adapted)
  • Extremely space-constrained designs where smaller packages like DFN are required

Check before use

  • Bus termination impedance
  • Signal integrity at 16Mbps
