TCAN337D Overview
A CAN transceiver is the physical-layer interface within a Controller Area Network. A CAN controller generates and interprets digital frames, while the transceiver converts that logic-level information into differential bus signals and receives bus states back into logic-compatible signals. The TCAN33x family is compatible with the ISO 11898 High-Speed CAN Physical Layer standard, as stated on the Texas Instruments product page.
The TCAN337D combines a 3.3 V operating range with a stated data rate of up to 1 Mbps and CAN FD support. Its supply current is listed as 180 mA in the supplied cross-reference data, while the receiver hysteresis is 120 mV. The 8-SOIC package is identified by DigiKey as a surface-mount package, and the family documentation states that the standard 8-pin SOIC packages support drop-in compatibility.
Typical bus applications include industrial automation equipment, embedded controllers, vehicle electronics, battery-powered instruments, and other 3.3 V systems that communicate over a high-speed CAN network. Because CAN is a multi-node differential bus, transceiver placement, termination, grounding, and controller compatibility remain important system-level considerations.
For a new PCB, place the transceiver close to the bus connector and CAN controller, provide a continuous ground reference, route the differential bus as a coupled pair, and install the required 120-ohm termination only at appropriate bus endpoints. Existing designs should verify voltage levels, pin mapping, transceiver mode, and timing before upgrading.

TCAN337D 8 pins Pin Configuration Guide
Pin configuration for TCAN337D (8 pins package). Pin numbering, functions, and connection diagrams are defined in the manufacturer datasheet. Refer to it for the exact footprint and soldering guidelines.
No detailed pinout data available for TCAN337D.
Refer to the datasheet for full pin configuration.
Typical Applications
TCAN337D is suitable for 6 applications: Industrial Automation CAN Network, Embedded Automotive Electronics, Battery-Powered Sensor Node, Robotics and Motor-Control Communications, Test and Measurement Equipment, Building and HVAC Control Network.
Industrial Automation CAN Network
The TCAN337D fits a 3.3 V industrial controller node that must connect to sensors, actuators, remote I/O, or another controller over a high-speed CAN bus. Its verified 3.0 V to 3.6 V supply range matches a 3.3 V rail, while CAN FD support and a maximum specified data rate of 1 Mbps are useful for communication between embedded control modules. The half-duplex interface connects one CAN controller to the shared bus rather than providing a separate full-duplex link. Place the transceiver near the controller and connector, route CANH and CANL as a differential pair, provide continuous ground, and apply termination according to the network topology. Validate industrial EMC, fault recovery, and temperature requirements across the full -40°C to 125°C range before production release.
Recommended
Embedded Automotive Electronics
TCAN337D is appropriate for a 3.3 V vehicle or accessory electronics node when the system uses a high-speed CAN physical layer and requires a compact 8-SOIC interface. The listed operating range of -40°C to 125°C provides a defined temperature envelope, while the 1 Mbps specification supports common high-speed CAN communication rates. CAN FD capability can be valuable when the controller and network stack support it, although the system designer must confirm the exact timing and bus-loading requirements. Automotive production designs should separately verify AEC-Q100 status, transient immunity, fault behavior, and supply filtering because those details are not supplied in the verified snippets. Use a low-impedance ground plane and protect the bus pins according to the vehicle electrical-environment requirements.
Recommended
Battery-Powered Sensor Node
The TCAN337D can serve as the CAN interface in a battery-powered 3.3 V sensor or measurement node where the system uses a shared bus instead of a point-to-point serial link. Its 3.0 V to 3.6 V operating range is suitable for regulated 3.3 V supplies, and the family documentation identifies low-power shutdown and standby modes as attractive for battery applications. The verified source does not provide quiescent current or shutdown-current figures, so power-budget calculations must use the manufacturer datasheet. For a compact instrument, route the bus connector directly to the transceiver, keep the CAN differential pair away from noisy analog and switching paths, and provide local decoupling at the supply pins. Wake and sleep behavior must be coordinated with the CAN controller to avoid bus-state conflicts during low-power operation.
Recommended
Robotics and Motor-Control Communications
The TCAN337D is a useful physical-layer interface for a 3.3 V robot controller distributing status and command data over CAN. A single CAN controller can use the half-duplex transceiver to communicate with motor drivers, encoders, remote joints, and safety-monitoring modules on a common bus. The specified 1 Mbps rate supports high-speed CAN networks, while the 8-SOIC package is convenient for conventional PCB assembly. In a motor environment, place the transceiver away from switching nodes and motor-current paths, maintain a solid ground plane, and use a controlled bus topology to minimize stubs. Verify whether the selected CAN controller supports the required CAN FD payload and timing, and test fault tolerance during motor startup, braking, and regenerative events. The provided data does not establish isolated-bus or automotive transient ratings.
Recommended
Test and Measurement Equipment
TCAN337D can be used in a 3.3 V test instrument, interface module, or programmable controller that communicates with external CAN equipment. The half-duplex CAN interface is useful for connecting a controller to analyzers, programmable supplies, fixtures, and laboratory automation systems. The verified operating range of -40°C to 125°C allows the same part family to be evaluated across wide environments, while the 8-SOIC package supports established surface-mount assembly. Use a short, controlled differential route from the transceiver to the external connector, maintain a continuous reference plane, and follow the bus termination plan recommended for the complete network. For instrumentation, isolate sensitive analog sections from the CAN return path and verify ground potential differences before connecting two separately powered nodes. Exact EMC, isolation, and loop-delay values require the manufacturer datasheet.
Recommended
Building and HVAC Control Network
The TCAN337D is suitable for a 3.3 V building-control node that connects a controller to room sensors, dampers, gateways, or energy-management modules over high-speed CAN. Its specified 3.0 V to 3.6 V supply range and -40°C to 125°C operating range support a broad range of indoor and embedded equipment environments. CAN FD capability can improve efficiency when controllers exchange larger status payloads, although the selected controller software and bus timing must support the feature. Place the transceiver at the network edge near the connector, route CANH and CANL as a pair over a continuous ground plane, and avoid long unprotected stubs. Use termination only at designated physical endpoints. Check cable length, node count, and fault behavior for the selected topology; the verified sources do not provide maximum bus length or connector pinout details.

Key Differentiators
- 3.3 V CAN FD interface (vs TCAN330D)
- Same verified 8-SOIC footprint (vs TCAN337DR)
- Half-duplex single-node interface (vs TCAN332D)
- Verified environmental range (vs TCAN334D)
Design Notes
Place the TCAN337D close to the CAN controller and the external CAN connector. Route CANH and CANL as a closely coupled differential pair over a continuous ground reference, and keep the pair away from switching power nodes, motor drivers, and high-current return paths. The verified package is 8-SOIC, so use the manufacturer's pinout and land pattern rather than inferring pin locations from a generic SOIC drawing.
Do not treat every TCAN33x order code as electrically identical without checking its datasheet. The verified data confirms the TCAN337D family, 3.0 V to 3.6 V supply range, 1 Mbps maximum data rate, 8-SOIC package, and 120 mV receiver hysteresis. Before substituting TCAN330D, TCAN332D, TCAN334D, or TCAN337DR, verify the exact pin functions, mode-control behavior, timing, and lifecycle status.
Provide local supply decoupling and route the transceiver ground directly to the system ground plane. The verified supply-current value is 180 mA, but the source does not identify whether this is a typical, maximum, or operating-condition value; do not use it alone for a complete regulator power budget. Confirm the datasheet limits, CAN bus load, controller supply current, and startup behavior before selecting the 3.3 V regulator.
Apply 120-ohm termination only at the intended endpoints of the CAN network, not at every node. Keep stubs short and use a topology compatible with the selected cable and controller. The verified sources identify ISO 11898 compatibility and a 1 Mbps specification, but maximum cable length, loop-delay limits, isolation requirements, and EMC test details are not provided and must be taken from the manufacturer datasheet.
Compliance Information
The supplied search results identify TCAN337D as an active 8-SOIC CAN transceiver, but they do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Confirm current declarations on the Texas Instruments product page and applicable manufacturer documentation.
