General Features

  • Fully ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant
  • Optimized for use in 12 V automotive systems
  • Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI), according to proposed EMC Standards IEC 62228-3 and SAE J2962-2
  • AEC-Q100 qualified
  • Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
  • Shorter propagation delay on the TJA1057B and TJA1057C variants supports larger network topologies
  • Variants with a VIO pin allow for direct interfacing with 3.3 V to 5 V microcontrollers. Variants without a VIO pin can interface with 3.3 V and 5 V-supplied microcontrollers, provided the microcontroller I/Os are 5 V tolerant.

Predictable and Fail-safe Behavior

  • Functional behavior predictable under all supply conditions
  • Transceiver disengages from bus when not powered (zero load)
  • Transmit Data (TXD) dominant time-out function
  • Internal biasing of TXD and S input pins


  • High ESD handling capability on the bus pins (8 kV IEC and HBM)
  • Bus pins protected against transients in automotive environments
  • Undervoltage detection on pins VCC and VIO
  • Thermally protected


  • Timing guaranteed for data rates up to 5 Mbit/s
  • Improved TXD to RXD propagation delay of 210 ns
