Dual Channel CAN SIC Transceiver with Standby Mode (ASIL B)
- 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 TJA1468 is a dual-channel 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 minimizes signal ringing to ensure reliable CAN FD communication at 5 Mbit/s and supports data rates up to 8 Mbit/s in larger or more complex topologies.
Compared with two single-channel SIC transceivers, the TJA1468 reduces overall system cost and bill-of-materials (BOM) size while providing ASIL B functional safety and bus-load capability compatible with CAN XL. It is a direct drop-in replacement for NXP's TJA1448, enabling an easy upgrade path for existing CAN and CAN FD 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 3.3 V to 5 V microcontrollers (compatible with TJA1448)
- Low electromagnetic emission (EME) and high electromagnetic immunity (EMI)
- Qualified according to AEC-Q100 grade 1
- Available in SO14 package and leadless HVSON14 package, much smaller BOM than 2x single CAN SIC
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 to 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 is 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
