8 Mbps CAN FD — what the data rate means for the bus
The TCAN1044AEVDRQ1 is a Texas Instruments CAN FD transceiver that pushes the data phase to 8 Mbps while keeping arbitration at the standard CAN bit rate. That 8 Mbps figure is the payload throughput during the data phase — the part handles the full ISO 11898-2:2016 CAN FD specification, so you get backward compatibility with classical CAN nodes on the same bus. The half-duplex 1/1 driver/receiver pair is the expected topology for a two-wire differential bus. The receiver hysteresis is 115 mV, providing a differential noise margin on the bus.
Automotive temperature grade — 150°C junction capability
AEC-Q100 qualification covers HBM ESD, latch-up, temperature cycling, and extended life test.
Package and footprint — 8-SOIC with standard pinout
Verify the moisture sensitivity level from the TI packing label before opening the sealed bag.
This is not a NRND or phase-out situation — the AEC-Q100 qualification and active status together mean it is a first-choice line-fit part, not a bridge-to-shrink. For dual-source or second-source options, see the FAQ below.
