Automotive CANbus physical layer — AEC-Q100 Grade 1 qualified
The Texas Instruments SN65HVDA1040AQDRQ1 is an automotive-grade CAN transceiver in an 8-SOIC package, specified for the 1 Mbps CAN 2.0 high-speed bus.
125 mV receiver hysteresis — bus noise margin for the automotive environment
The 125 mV hysteresis on the receiver inputs provides a defined switching threshold that rejects common-mode noise on the CAN bus — a practical concern in automotive harnesses where ignition noise and motor-drive coupling can corrupt the differential signal. This is a datasheet-typical figure that directly affects the bus's bit-error rate in a noisy electrical environment.
