I would like to ask what is the difference between these two chips TCAN1042HVDR and TCAN1042VDRBRQ1。
Hi Kevin,
The 'H', 'G', and 'V' characters indicate higher bus fault protection, 5Mbps support, and internal voltage translation support respectively. Section 5 on the datasheet outlines the different options for feature combinations:
"D" vs "DRB" indicate the device package as SOIC or VSON respectfully. The presence or absence of 'R' denote if the device will ship in a tape and reel (large quantity only) or in a tube. This information is displayed in the ordering section on the store page:
Lastly, the "Q1" denotes that the device is automotive qualified to the AEC-Q100 standard for temperature and reliability. Read more about this at the link below:

Let me know if you have any more questions.
Regards,
Eric Schott
