What this CAN transceiver does on your board
It handles the differential transmit and receive signals, provides bus-fault protection, and includes a 100 mV receiver hysteresis for noise immunity. Typical applications include automotive body electronics, industrial automation networks, and any CAN 2.0B bus node that needs a robust physical-layer interface in a compact 8-SOIC footprint.
A 125°C-rated transceiver gives headroom for self-heating in a sealed enclosure without derating the bus speed.
1 Mbps data rate and 100 mV hysteresis — bus timing and noise margin
Rated for 1 Mbps, this transceiver meets the maximum bit rate defined by CAN 2.0B. The 100 mV receiver hysteresis filters out differential noise on the bus, reducing the chance of false bit detection in electrically noisy environments like factory floors or vehicle power trains. For CAN FD applications, the 1 Mbps ceiling means this part is limited to standard CAN frames only — it cannot handle the faster data phase of CAN FD.
For dual-sourcing or supply resilience, the SN65HVD230D is a pin-compatible sibling in the same 8-SOIC footprint — the key difference being the supply voltage range (the 230D operates from 3V to 3.6V as well, but check the specific datasheet for minor parametric deltas).
