Drivers

RS-485half-duplexautomotiveAEC-Q100±70 V fault protection1 MbpsSOIC-8

SN65HVD1781A-Q1 is an automotive-qualified, fault-protected half-duplex RS-485 transceiver for 3.3 V or 5 V systems and data rates up to 1 Mbps.

Best for

  • Automotive RS-485 networks
  • Fault-exposed two-wire differential buses
  • Infotainment and instrument-cluster communications

Avoid if

  • A data rate above 1 Mbps is required
  • An isolated transceiver is required
  • The application requires operation above 105°C with a 5 V supply

Check before use

  • Verify A/B bus polarity and DE/RE control logic
  • Use termination at both cable ends as appropriate
  • Place a 100 nF bypass capacitor close to VCC
  • Assess external TVS protection for higher-energy transients
