TJA1462BTK/0Z - 8Mbit/s CAN SIC Transceiver | NXP
Teilenummer: TJA1462BTK/0Z ✓ AktivTJA1462BTK/0Z Übersicht
A CAN transceiver is an interface IC that converts logic-level signals from a CAN controller into differential bus signals and converts received bus signals back into controller-compatible logic. Within the network hierarchy, the TJA1462 belongs to the CAN transceiver family, interface IC category, and broader semiconductor and automotive communication electronics markets. Its SIC function reduces signal ringing and improves bit-timing symmetry, helping preserve communication reliability on challenging bus networks.
The principal features include support for CAN FD data rates up to 8 Mbit/s, CAN Signal Improvement Capability, and a dedicated Standby operating mode. The 8-HVSON package supports compact PCB layouts, while its 3 x 3 mm land pattern helps reduce the space required by the physical bus interface. The TJA1462 family is also documented as a simple replacement for NXP TJA1042 and TJA1044 high-speed Classical CAN and CAN FD transceivers, allowing existing hardware and software architectures to be retained during selected upgrades.
According to the NXP TJA1462 data sheet, the device is intended to improve bit-timing symmetry and suppress ringing on the CAN bus. These characteristics are particularly relevant when a network operates at high CAN FD rates, when bus topology creates reflections, or when additional signal margin is required between the physical transceiver and the CAN controller. The transceiver’s principal design trade-off is that users must follow the NXP pin configuration, supply, decoupling, and bus-connection guidance exactly rather than treating it as a generic high-speed CAN interface.
Typical uses include CAN FD gateways, automotive domain controllers, body and comfort modules, electric-vehicle control systems, industrial vehicle networks, and CAN-based diagnostic equipment. In these systems, the TJA1462 serves as the physical-layer interface between a CAN controller and the differential CAN_H and CAN_L conductors. Its SIC implementation can improve signal quality without requiring the surrounding CAN protocol stack or application software to be redesigned.
For PCB implementation, use the package-specific pin configuration and land pattern from the NXP data sheet, place the required supply and decoupling capacitors close to their assigned pins, and route CAN_H and CAN_L as a controlled-impedance differential pair. Keep the bus and transceiver connection away from sources of high-energy interference, and review termination, common-mode behavior, and standby-control requirements at the system level.
This page consolidates the manufacturer’s CAN SIC, ISO 11898-2:2024, 8 Mbit/s, Standby-mode, and package information into an application-focused engineering reference. It also organizes drop-in family alternatives and implementation guidance that support faster component selection, PCB planning, and CAN network upgrade decisions.

Automotive CAN FD Domain Controllers
The TJA1462BTK/0Z fits a domain controller interface that must connect a CAN controller to a physical CAN FD bus. Its CAN Signal Improvement Capability reduces ringing, while improved bit-timing symmetry supports reliable communication at rates up to 8 Mbit/s. The reduced signal margin loss is particularly valuable on vehicle networks that combine longer harness branches, multiple nodes, and high-traffic CAN FD domains. Its 8-HVSON 3 x 3 mm package also supports compact controller-board placement. Confirm the exact exposed-pad and land-pattern requirements in the NXP data sheet before routing the PCB.

Electric Vehicle Powertrain Communication
The TJA1462BTK/0Z is suitable for CAN FD links carrying control and diagnostic data among electric-vehicle battery, inverter, and vehicle-controller modules. Support for data rates up to 8 Mbit/s provides bandwidth for more frequent vehicle messages than Classical CAN, while CAN SIC helps reduce ringing on a complex harness. The ISO 11898-2:2024 SIC implementation and improved bit-timing symmetry can increase signal margin without changing the higher-layer CAN protocol. In a compact electronic control unit, the 8-HVSON 3 x 3 mm package helps conserve board area, although thermal and exposed-pad layout must follow the manufacturer guidance.

CAN FD Diagnostic Gateways
The TJA1462BTK/0Z can provide the physical-layer connection in a diagnostic gateway that bridges vehicle CAN FD segments to test equipment or other vehicle networks. Its 8 Mbit/s capability supports faster CAN FD payload exchange, and CAN SIC reduces the effects of ringing and timing asymmetry on reflective bus segments. Standby mode provides an additional low-activity state for systems that manage partial network wake-up. The compact 8-HVSON package fits gateway boards where connector access and routing space are constrained. Use the NXP pinning and application guidance to place the transceiver, maintain bus symmetry, and implement the standby-control function.

Industrial Vehicle CAN Networks
The TJA1462BTK/0Z supports CAN FD communication in industrial vehicles such as construction, agricultural, and material-handling equipment where controllers exchange sensor and actuator data over long harnesses. Such installations can produce reflections and timing distortion that become more significant as data rates increase. The device’s CAN Signal Improvement Capability and improved bit-timing symmetry address those physical-layer concerns while retaining support for Classical CAN nodes. Its 8-HVSON 3 x 3 mm package supports compact controller modules. The design should still include suitable bus protection, proper common-mode handling, and all decoupling recommended in the manufacturer data sheet.
Empfohlen
Body and Comfort Control Modules
The TJA1462BTK/0Z is appropriate for body and comfort modules that participate in CAN FD communication while sharing a vehicle network with numerous other electronic control units. Reducing bus ringing and improving bit-timing symmetry can help maintain communication margin in dense electrical environments. Its Standby mode is useful for modules designed to reduce activity when their associated network is inactive. The 8-HVSON package is compact enough for space-constrained node electronics, and its 8 Mbit/s rating permits participation in faster CAN FD segments. Confirm module-level thermal requirements and qualification details before production release.
Empfohlen
CAN FD Communication Hubs
The TJA1462BTK/0Z can serve each physical CAN FD interface in a communication hub or multi-channel gateway. CAN Signal Improvement Capability reduces ringing on bus wiring, and the improved bit-timing symmetry helps maintain reliable data transfer at rates up to 8 Mbit/s. The same family supports Classical CAN, allowing a gateway design to combine legacy and CAN FD channels while maintaining a consistent transceiver approach. Its 8-HVSON 3 x 3 mm footprint supports dense multi-channel boards. Separate CAN_H and CAN_L routing, controlled differential impedance, suitable termination, and the NXP-prescribed decoupling layout remain essential to the expected performance.

Designhinweise
Use the NXP TJA1462BTK HVSON8 pin configuration and land pattern as the authoritative PCB basis. The package has eight terminals in a 3 x 3 mm surface-mount outline, so placing it as though it were an SO8 can cause track, exposed-pad, and soldering errors. Assign every pin from the package-specific diagram and review the manufacturer’s recommended land pattern before releasing artwork.
Route CAN_H and CAN_L as a controlled-impedance differential pair and keep their geometry as symmetrical as practical. Minimize stub branches, vias, and unnecessary test-point discontinuities because these structures can add reflections that counteract the benefit of CAN Signal Improvement Capability. Follow the NXP PCB guidance for the separation between the transceiver, connector, protection components, and system ground.
Place every bypass capacitor required by the NXP application guidance directly beside its associated supply pin and ground return. Keep the high-current return path compact and use an uninterrupted ground plane beneath the device where the package construction permits. Confirm the transceiver’s supply limits, capacitor voltage ratings, startup behavior, and Standby-mode current from the manufacturer data sheet before finalizing the power tree.
Do not assume that all TJA1462 package variants are interchangeable: the family includes SO8 and HVSON8 versions with different footprint and thermal-pad requirements. Also avoid treating TJA1462ATK and TJA1462BTK ordering variants as identical without checking their qualification, temperature, and commercial details. Verify the exact MPN suffix on the purchase order and compare the selected variant against the approved schematic and PCB revision.
