TJA1040T/CM 概述
A CAN transceiver is a physical-layer interface IC within the broader interface-IC hierarchy. It converts the controller’s digital logic signals into differential bus signaling and converts differential bus levels back into logic-compatible receive signals. The TJA1040 is intended primarily for high-speed passenger-car CAN networks, where robust differential signaling, standby control, and electromagnetic compatibility are important.
The verified manufacturer information identifies differential transmission, differential reception, high-speed operation up to 1 MBaud, and standby-mode capability as principal device features. The distributor record identifies the TJA1040T/CM,118 ordering form as an 8-pin SO CAN-bus transceiver. Detailed electrical limits, loop-delay values, bus-fault behavior, and package dimensions were not supplied in the verified extract and therefore require confirmation from the manufacturer datasheet before design release.
Typical uses include passenger-vehicle body and powertrain CAN networks, automotive control modules, CAN gateways, and industrial equipment that uses a 5 V CAN physical layer. The transceiver is intended to operate with a compatible CAN controller rather than as a standalone bus controller. Its differential bus interface supports robust communication over cable networks, while the standby function can reduce activity when the node is not communicating.
Designers should preserve the pin assignment, supply decoupling, CANH/CANL routing, termination, and common-mode protection described by the manufacturer. The verified source set does not include the complete pinout, absolute maximum ratings, thermal data, or EMC test values, so those details must not be inferred. This page combines official NXP information with distributor records and explicitly marks unavailable parameters rather than estimating them.
TJA1040T/CM is a legacy EoL-positioned part according to the supplied migration context. For new designs, engineers should compare it with current NXP or third-party CAN transceivers and verify pin, electrical, lifecycle, and qualification compatibility before treating any replacement as drop-in.

典型应用
TJA1040T/CM 适用于 6 应用s: Passenger-Car Body Control CAN, Automotive Powertrain CAN Interface, CAN Gateway Module, Industrial CAN Sensor Network, Vehicle Diagnostic Interface, Embedded Automotive Controller CAN Port.
Passenger-Car Body Control CAN
The TJA1040T/CM fits body-control modules and passenger-car electronics that connect a CAN controller to a high-speed physical bus. Its stated capability reaches 1 MBaud, while differential transmit and differential receive provide the bus-side interface expected by CAN controllers. The 8-pin SO package supports compact PCB placement, and standby mode can help reduce activity in a node that is not communicating. Design the CANH and CANL routing as a differential pair, provide the required bus termination, and verify the exact mode-control and timing requirements against the NXP datasheet before production.
推荐
Automotive Powertrain CAN Interface
TJA1040T/CM is appropriate for a 5 V CAN physical-layer interface in an automotive module when its operating envelope, EMC behavior, and fault handling meet the vehicle program requirements. The verified manufacturer description specifically targets high-speed passenger-car applications up to 1 MBaud and provides differential signaling in both directions. The device is not a CAN protocol controller, so the host MCU or dedicated controller must generate and interpret CAN frames. Keep the CAN bus pins away from noisy power paths, use approved protection networks, and validate radiated and conducted emissions with the complete vehicle or module test setup.
推荐
CAN Gateway Module
A CAN gateway can use the TJA1040T/CM as the physical-layer endpoint between an embedded CAN controller and a longer differential bus. The 1 MBaud capability makes it suitable for high-speed communication among automotive or industrial subsystems, while standby mode provides a possible power-management state. The gateway designer should account for bus termination, common-mode voltage, propagation delay, node contention, and fault recovery. Because the verified source does not supply complete loop-delay and absolute-maximum data, obtain the official datasheet before setting timing budgets or selecting protection components.
推荐
Industrial CAN Sensor Network
The TJA1040T/CM can provide the physical-layer interface for a 5 V industrial CAN network connecting a controller to remote sensors, actuators, or service modules. Differential signaling helps reject common-mode disturbance compared with a single-ended interface, and the 1 MBaud class is suitable for high-speed control traffic. The transceiver must still be paired with a CAN protocol controller, proper termination, and industrial surge protection. Validate cable length, topology, grounding, EMC, and fault behavior against the complete installation because those system parameters are not specified in the verified extract.
推荐
Vehicle Diagnostic Interface
A diagnostic connector or service module can use TJA1040T/CM as the CAN bus-side transceiver when the system requires a high-speed physical layer and differential bus signaling. The device is intended for passenger-car CAN networks and supports standby mode, which can be useful during inactive periods. The host processor must implement the CAN protocol and diagnostics above the physical layer. Keep the transceiver close to the connector protection components, maintain a controlled return or ground strategy, and test bus fault cases such as shorted lines and dominant/recessive states using the manufacturer’s absolute maximum and fault-recovery information.
推荐
Embedded Automotive Controller CAN Port
TJA1040T/CM is suitable for an embedded automotive controller that needs a conventional high-speed CAN physical interface. Its differential transmitter communicates with the bus, and its differential receiver returns logic-compatible signals to the controller, leaving frame handling and arbitration to the host. The 8-pin SO package helps reduce board area in compact control units, while the 4.75 V to 5.25 V supply specification aligns with a regulated 5 V rail. Confirm decoupling, mode pins, timing, and thermal limits from the official datasheet, and compare current active parts for new production programs.

- Legacy NXP high-speed CAN physical-layer role （对比 TJA1044CT/0Z)

设计说明
Route CANH and CANL as a close differential pair with continuous ground reference, minimizing stub branches and asymmetry between the transceiver and connector. Keep the CAN bus traces away from switching power inductors, high-current motor returns, and other aggressive EMI sources. The supplied data does not provide a reference PCB layout or controlled-impedance values, so use the manufacturer datasheet and board-level EMC testing for final geometry.
Do not treat TJA1040T/CM as a CAN protocol controller. It only provides the physical-layer transceiver functions; a CAN controller or MCU must handle frame generation, arbitration, error handling, and higher-layer protocols. Also verify the exact TJA1040T/CM suffix and package before ordering because distributor records use TJA1040T/CM,118 while some cross-references use TJA1040T or manufacturer ordering variants.
Use the verified 4.75 V to 5.25 V supply range as the design boundary, and place the required local decoupling directly at the transceiver supply pins according to the official datasheet. The verified extract does not provide supply-current limits, transient requirements, or absolute maximum voltage, so do not select capacitors or protection components from generic assumptions. Validate startup, standby current, and conducted emissions in the final module.
A replacement should not be approved by package name alone. Compare CANH/CANL pin mapping, RXD output behavior, standby or mode-control logic, propagation delay, bus-fault recovery, common-mode range, supply voltage, and qualification requirements. The supplied cross-reference data identifies possible candidates but also warns that not all common CAN replacements are drop-in; preserve an engineering review record for any substitution.
合规信息
The verified search results identify automotive and passenger-car applications but do not provide extracted RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Compliance must be confirmed from the current NXP product documentation or supplier certificates.
