DeviceNet™ CAN transceiver — what the 1 Mbps and 160 mV hysteresis mean on a real bus
It drives the CANH and CANL lines at up to 1 Mbps, which is the full speed for CAN 2.0 — enough for real-time actuator networks in industrial automation, PLC racks, and sensor arrays where the bus length stays under 40 m. The 160 mV receiver hysteresis filters out noise on a shared twisted pair without external filtering, so the bus stays clean even when the cable picks up motor-drive hash.
Supply rail and 5 V logic compatibility
The logic-side interface is 5 V tolerant, so it mates directly with a 5 V MCU's CAN controller without level shifters. If your design uses a 3.3 V controller, you will need a voltage translator or a 3.3 V-rated CAN transceiver instead — this part's input thresholds are not 3.3 V compatible.
Surface-mount only, no through-hole variant.
Design-in checklist
One driver and one receiver per package. The half-duplex architecture means the bus is shared — the CAN controller manages arbitration, not the transceiver. The 1 Mbps data rate is the maximum; if your bus runs at 125 kbps or 250 kbps, the part handles those without issue. The 160 mV hysteresis is fixed, so there is no adjustment pin. Decouple the supply with a 100 nF ceramic close to pin 8 (VCC) and a bulk 10 µF on the board; the SOIC-8 footprint does not have a thermal pad, so keep the ambient below 85°C or derate the bus load.
