CAN FD transceiver built for the 5V automotive bus
The TCAN1042GVDRQ1: It supports data rates up to 5 Mbps, which covers both classical CAN (up to 1 Mbps) and CAN FD (flexible data-rate) frames where the payload phase runs faster than the arbitration phase.
5 Mbps data rate — why it matters for CAN FD designs
The 5 Mbps data rate covers both classical CAN (up to 1 Mbps) and CAN FD frames. The 1/1 driver/receiver count means one CAN node per package.
Supply voltage and cold-crank margin
The supply range of 4.5V to 5.5V is the standard 5V CAN bus rail, with the 4.5V low end providing headroom during automotive cold-crank events where the battery voltage can sag below 5V. This avoids bus-off or brownout resets that a 4.75V minimum part might suffer in the same scenario.
AEC-Q100 and temperature grade — deployment context
The 125°C ceiling covers exhaust-adjacent mounting and high-ambient powertrain compartments, while the -55°C floor handles cold-soak in northern-climate vehicles.
Lifecycle status — active, no LTB risk
The base product number TCAN1042 is a current TI family with broad distribution support.
