CAN FD transceiver for 5 Mbps bus lines
The TCAN4420DR is a single-channel CANbus transceiver from Texas Instruments that handles data rates up to 5 Mbps, making it suitable for CAN FD (flexible data-rate) networks where payload throughput exceeds the classical 1 Mbps limit.
5 Mbps data rate and noise margin
The 5 Mbps data rate supports CAN FD frames where the arbitration phase runs at 500 kbps or 1 Mbps and the data phase switches to a higher bit rate. The 200 mV receiver hysteresis provides a clean logic transition on the RXD output even when the differential bus signal carries common-mode noise or reflections from unterminated stubs — useful when the physical layer runs through a vehicle harness or a factory-floor cable tray.
