2nd Generation CAN SIC Transceiver with Sleep Mode (ASIL B and 1.8 V VIO)
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
The TJA1467 is a high-performance CAN SIC (Signal Improvement Capability) transceiver with standby mode, designed for next-generation automotive and industrial CAN networks. Fully compliant with ISO 11898-2:2024 and SAE J22841 through J2284-5, it minimizes signal ringing to ensure robust, reliable CAN FD communication at 5 Mbit/s and supports data rates up to 8 Mbit/s in large and complex topologies.
Compared to the TJA1463, the TJA1467 delivers a more cost-effective solution while adding ASIL B functional safety support, an extended Vbat operating range, and CAN XL-compatible bus-load capability. It remains fully backward compatible with NXP's established CAN transceiver families, including the TJA1043, TJA1443 and TJA1463, ensuring seamless integration into existing CAN and CAN FD system designs.

Features
General Features
- ISO 11898-2:2024, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant
- CAN FD communication up to 8 Mbit/s
- VIO input for interfacing with 1.8 V, 3.3 V and 5 V microcontrollers (compatible with TJA1462A)
- Low electromagnetic emission (EME) and high electromagnetic immunity (EMI)
- Qualified according to AEC-Q100 grade 1
- Available in SO14 package and leadless HVSON14 package
Signal Improvement and CAN XL Ready
- Implements CAN SIC as defined in ISO 11898-2:2024 third edition to significantly reduce signal ringing effects on a network
- Tighter bit timing symmetry performance allowing more times to reduce signal ringing
- Max wake-up-pattern time shortened to 1.45 us
- Extended bus load range (45 Ω - 65 Ω) to cover both CAN SIC and CAN XL fast mode
Fail-Safe and Functional Safety
- ASIL B rated according ISO 26262, providing all required functional safety documentation, such as safety manual, FMEDA, etc.
- Undervoltage detection with defined handling on all supply pins
- Full functionality guaranteed from the undervoltage detection thresholds up to the maximum limiting voltage values
- Defined behavior below the undervoltage detection thresholds
- Transceiver disengages from the bus (high-ohmic) when the supply voltage drops below the off-mode threshold
- Internal biasing of TXD and mode selection input pins to enable defined fail-safe behavior
