  • Supports classic CAN up to 1 Mbps and FD (flexible data rate) up to 5 Mbps.
  • Protection features.
  • DC Bus Fault Protection Voltage: ±58 V.
  • IEC ESD tolerance on bus pins: ±8 kV.
  • HBM ESD tolerance on bus pins: ±10 kV.
  • Driver dominant time out (TXD DTO).
  • Undervoltage protection on VCC1 and VCC2.
  • Common-mode voltage range: ±12 V.
  • Ideal passive, high impedance b.
