The supply range of 4.5V to 5.5V is standard for CAN physical layers, but note that the logic interface is 5V-tolerant — if you're pairing it with a 3.3V microcontroller, you'll need to check the VIO pin (if present on the variant) or add level translation. The 50 mV receiver hysteresis helps reject bus noise in electrically noisy environments like motor drives or engine bays. The narrow SOIC footprint is common for CAN transceivers, so board layout reuse across variants is straightforward.","metaTitle":"TCAN1043DRQ1 CAN Transceiver, AEC-Q100, 2 Mbps, 14-SOIC","metaDescription":"TCAN1043DRQ1 is an automotive AEC-Q100 CAN transceiver from TI.
