Chip Resistor - Surface Mount

RS-485RS-422half duplex5 VMSOP-8500 kbps1/8 unit load

SN65HVD78DGKR-TUDI is a 5 V, half-duplex RS-485/RS-422 transceiver in MSOP-8 for low-speed industrial multidrop buses up to 500 kbps.

Best for

  • 5 V half-duplex RS-485 networks
  • Industrial multidrop communication
  • Applications needing low-slew-rate bus signaling

Avoid if

  • A 3.3 V-only transceiver is required
  • Data rate exceeds 500 kbps
  • Verified compliance or lifecycle status is mandatory but unavailable

Check before use

  • Use 120 Ohm termination at the ends of a matched RS-485 trunk where appropriate.
  • Keep bus stubs short to reduce reflections.
  • Validate the family datasheet against the exact ordered part.
