TJA1055T/2Z - 125 kBd Fault-Tolerant CAN Transceiver | NXP
MPN: TJA1055T/2Z ✓ सक्रियTJA1055T/2Z अवलोकन
A CAN transceiver is an interface IC that connects a host controller to a differential CAN network. It belongs to the communication interface hierarchy: CAN transceiver > bus transceiver > interface IC > semiconductor. Unlike a generic transceiver, this device is designed around the electrical behavior and fault tolerance requirements of low-speed CAN systems, where dependable operation during wiring faults and disturbed bus conditions is important.
Key documented features include enhanced fault-tolerant CAN operation, support for data rates up to 125 kBd, and use in passenger-car CAN networks. The verified distributor records also identify the device as a one-channel, half CAN-bus transceiver in a 14-SO package. The NXP product page identifies TJA1055T as active and lists reel-reel packing with a minimum package quantity and minimum order quantity of 2,500 pieces.
The TJA1055T/2Z performs the physical signaling required between the CAN controller and the bus while providing the fault-tolerance behavior expected in automotive environments. Its use of a dedicated bus interface allows the controller to send and receive frames without implementing analog bus-level signaling directly. Detailed thresholds, loopback behavior, supply current, and absolute maximum ratings remain because they were not included in the supplied verified records.
Typical uses include passenger-car body and comfort systems, door modules, climate-control controllers, lighting controllers, instrument clusters, and other low-speed CAN nodes. It is most appropriate where the network operates at 125 kBd or below and the design requires a dedicated high-reliability CAN physical-layer device rather than a general-purpose differential transceiver.
When designing a PCB around the TJA1055T/2Z, verify the complete NXP datasheet pinout, transceiver termination requirements, supply decoupling, and bus-fault behavior before layout release. The supplied search records establish the 14-SO package designation but do not expose a verifiable numbered pin table, so this page does not infer pin names or connectivity. Maintain the manufacturer-specified CAN bus topology and provide the required local decoupling and protection appropriate to the vehicle network.

सामान्य अनुप्रयोग
TJA1055T/2Z के लिए उपयुक्त है 6 अनुप्रयोगs: Passenger-Car Body Control Modules, Door and Seat Control Modules, Climate-Control Controllers, Automotive Lighting Control, Instrument Cluster Communication, Low-Speed Industrial CAN Networks.
Passenger-Car Body Control Modules
The TJA1055T/2Z fits low-speed passenger-car body networks because it is an enhanced fault-tolerant CAN transceiver rated for operation up to 125 kBd. It can sit between a vehicle CAN controller and the physical bus, translating controller logic into differential bus signaling. The 14-SO package supports compact controller-board layouts. According to NXP, the device is specifically intended for passenger-car applications, although exact qualification, EMC, and wiring-fault requirements should be confirmed for the target vehicle platform.
अनुशंसित
Door and Seat Control Modules
Door-zone and seat-control electronics commonly exchange commands over low-speed CAN rather than high-bandwidth automotive Ethernet. The TJA1055T/2Z provides the CAN physical layer for such nodes, with documented support up to 125 kBd and a 5 V supply range of 4.75 V to 5.25 V. Its fault-tolerant implementation is relevant when harness faults or disturbed bus levels must be tolerated. The compact 14-SO outline helps conserve board area compared with larger through-hole transceiver solutions.
अनुशंसित
Climate-Control Controllers
A climate-control module must exchange sensor commands and actuator requests over a reliable vehicle network while operating from an automotive 5 V rail. The TJA1055T/2Z matches the documented 4.75 V to 5.25 V supply range and provides CAN physical-layer signaling up to 125 kBd. Placing it between the local CAN controller and the bus simplifies protocol handling, while the enhanced fault-tolerant architecture is useful in distributed vehicle electrical systems where wiring disturbances can affect communication.
अनुशंसित
Automotive Lighting Control
Exterior and interior lighting controllers benefit from a deterministic, fault-tolerant bus interface for distributing lamp commands and receiving status information. The TJA1055T/2Z is appropriate for CAN networks operating at or below 125 kBd, as explicitly stated by NXP for passenger-car applications. Its 14-SO package supports dense PCB placement, while its dedicated CAN interface avoids burdening the host controller with analog bus-line signaling. Protection components and the final transceiver must be reviewed against the vehicle's transient and wiring requirements.
अनुशंसित
Instrument Cluster Communication
Instrument clusters receive status information from multiple vehicle modules and therefore benefit from a dedicated, fault-tolerant CAN physical layer. The TJA1055T/2Z supports communication rates up to 125 kBd and operates from a nominal 5 V supply with a documented 4.75 V to 5.25 V range. It can provide the bus-side interface for a cluster CAN controller. Because cluster boards may be particularly sensitive to EMC and ground-offset conditions, PCB layout, bus termination, protection, and qualification requirements must follow the complete NXP documentation and vehicle specification.
अनुशंसित
Low-Speed Industrial CAN Networks
The TJA1055T/2Z can also serve low-speed CAN nodes in industrial equipment where the bus rate does not exceed 125 kBd and a fault-tolerant physical layer is desired. Its 4.75 V to 5.25 V supply range suits 5 V embedded systems, and the 14-SO package is convenient for compact controller boards. The original manufacturer positioning is automotive, so industrial use should be conditioned on thermal, EMC, safety, and qualification requirements that fall outside the verified excerpts.

डिज़ाइन नोट्स
Confirm the numbered 14-SO pin assignments from the NXP datasheet before routing the PCB. Place the transceiver and its required bypass capacitance at the shortest practical distance from the device supply pins, with a low-impedance ground return. The verified excerpts do not include the pinout, capacitor values, or exposed-pad requirements, so the layout must not be finalized from the package name alone.
Do not substitute TJA1054T as a direct drop-in part merely because it is a related CAN transceiver. The verified comparison result states that TJA1054T and TJA1055T have consistent functional characteristics but inconsistent main parameters and a modified circuit structure. Confirm ordering suffixes, temperature ranges, bus timing, fault behavior, and pin-level connectivity for any proposed alternative.
Use the manufacturer-recommended CAN bus routing and termination arrangement to minimize radiated emissions and susceptibility to external noise. Keep the CAN_H and CAN_CAN_L conductors as a closely coupled differential pair, avoid long unprotected branches, and place any external protection close to the connector. Exact spacing, stub limits, and protection-device values require the complete datasheet and board-level EMC validation.
The verified supply range is 4.75 V to 5.25 V, so the TJA1055T/2Z requires a regulated 5 V rail within that tolerance. Verify the transceiver's worst-case supply current, transient response, and local bypass requirements from the full manufacturer data before sizing the rail. The published $1.15 budgetary price at 1,000 pieces and 10-week lead time should be separated from component-availability and lifecycle decisions.
अनुपालन जानकारी
The supplied verified records describe the product as intended for passenger-car applications but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance must be confirmed from the current NXP product declaration or manufacturer documentation.
