The AEC-Q100 stamp is the gate for any automotive tier-1 or OEM BOM. Without it, a transceiver gets rejected at the PPAP stage. The 50 mV receiver hysteresis helps reject bus noise in electrically noisy environments like a motor drive or an engine bay. The 2 Mbps data rate supports CAN FD frames without re-clocking the network. If your design is still on classical CAN at 500 kbps or 1 Mbps, this part runs that too — it is backward-compatible. The single-ended supply rail at 5 V is the standard CAN physical layer; do not try to run it at 3.3 V, because the common-mode range and driver output levels are specified for 5 V only.
