Key Differentiators

Fast loop times for highly loaded networks (vs MCP2551-I/SN)
Pin-to-pin compatible with TCAN1057A-Q1 for CAN FD upgrade (vs SN65HVD256DR)
5V operation with VIO pin for 3.3V logic (vs SN65HVD234DR)

Design Notes

Place the SN65HVD255DR close to the CAN connector to minimize stub length. Use a 120-ohm termination resistor at both ends of the bus. Keep the differential pair (CANH and CANL) tightly coupled and routed with controlled impedance (typically 120 ohms differential).

Bypass the VCC pin with a 100nF ceramic capacitor placed as close as possible to the pin. Additionally, a 10uF bulk capacitor may be needed if the supply is shared with other components. Ensure the supply voltage is within 4.5V to 5.5V.

Do not forget to connect the VIO pin if the microcontroller operates at 3.3V. The VIO pin sets the I/O level for TXD and RXD. If left floating, the device may not interface correctly with 3.3V logic. Also, ensure the STBY pin is properly biased for normal operation.
