The TJA1464 is a CAN SIC (Signal Improvement Capability) transceiver with standby mode, designed for high‑speed automotive and industrial CAN networks. Fully compliant with ISO 11898‑2:2024 and SAE J2284‑1 through J2284‑5, it reduces signal ringing to enable reliable CAN FD communication at 5 Mbit/s, and supports data rates up to 8 Mbit/s in larger and more complex network topologies.
Compared to the TJA1462, the TJA1464 provides a more cost‑effective solution while adding ASIL B functional safety and extended bus‑load capability compatible with CAN XL. It is fully backward compatible with NXP’s widely adopted CAN transceivers, including the TJA1042, TJA1044, and TJA1462, making it easy to integrate into existing CAN and CAN FD system designs.

- VIO input for interfacing with 3.3 V to 5 V microcontrollers (compatible with TJA1462A)
- Low electromagnetic emission (EME) and high electromagnetic immunity (EMI)
- Qualified according to AEC-Q100 grade 1
- Available in SO8 package and leadless HVSON8 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 time 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
