Key Features
- AEC-Q100 Grade 1 qualified for automotive reliability across -40°C to +150°C junction temperature range
- Supports CAN FD data rates up to 8 Mbps, 4× faster than classic CAN at 2 Mbps
- ±58 V bus fault protection guards against wiring faults and load-dump transients
- Loop delay symmetry <15 ns reduces bit-timing errors in high-speed CAN FD frames
- Silent mode and TXD dominant-state timeout protect the bus from single-node failures
Applications
TCAN1042HDRQ1 is widely deployed in automotive body control modules, ADAS sensor nodes, and powertrain ECUs where ISO 11898-2 CAN FD connectivity at up to 8 Mbps is required. Its ±58 V fault protection makes it suitable for 12 V and 24 V vehicle architectures that experience load-dump or wiring-short events. Industrial designers also choose it for factory automation gateways where AEC-Q100 Grade 1 robustness and a compact 8-pin SOIC footprint ease board integration.

Frequently Asked Questions
What is the maximum CAN FD data rate supported by TCAN1042HDRQ1, and how does it compare to classic CAN?
TCAN1042HDRQ1 supports CAN FD data-phase bit rates up to 8 Mbps, which is 4 times faster than the 2 Mbps maximum of classic CAN. This higher throughput enables automotive ECUs to transfer larger data frames within tighter real-time windows, benefiting ADAS and diagnostics applications that move large payloads over the vehicle network.
How does TCAN1042HDRQ1 protect against bus faults in a 12 V automotive wiring harness?
The device provides ±58 V bus fault protection on both CANH and CANL pins, covering load-dump transients and wiring shorts to battery or ground in 12 V and 24 V vehicle systems. This exceeds the ±25 V minimum required by ISO 11898-2, giving designers a comfortable margin without external protection components.
Which automotive temperature and reliability grade does TCAN1042HDRQ1 meet, and what junction temperature range does that imply?
TCAN1042HDRQ1 is AEC-Q100 Grade 1 qualified, requiring operation across a -40°C to +125°C ambient temperature range with a junction temperature rating up to +150°C. This grade is standard for under-hood automotive electronics where thermal stress from engine heat and high ambient conditions is continuous.
When would an engineer choose TCAN1042HDRQ1 over a non-automotive CAN FD transceiver such as TCAN1042?
TCAN1042HDRQ1 is the AEC-Q100 Grade 1 screened variant of the TCAN1042 family, making it the required choice for automotive production builds where traceability and qualification documentation are mandatory. Both devices share the same 8-pin SOIC package and 8 Mbps data rate, so the board design is identical; the distinction is purely the qualification tier and associated product-change notification controls.
What supply voltage does TCAN1042HDRQ1 require, and can it interface directly with 3.3 V microcontrollers?
The bus-side VCC supply operates from 4.5 V to 5.5 V, but the logic-interface pins (TXD, RXD, and mode controls) are compatible with both 3.3 V and 5 V logic levels, allowing direct connection to a 3.3 V automotive microcontroller without level-shifting circuitry.
