TCAN337GD - 3.3V 5Mbps CAN FD Transceiver | Texas Instruments
Артикул: TCAN337GD ✓ АктивенTCAN337GD Обзор
A CAN transceiver is an interface integrated circuit that converts between a logic-level microcontroller bus and the differential CANH and CANL bus signals. The CAN FD protocol extends conventional CAN with faster data phases and larger payloads while retaining the familiar CAN network architecture. In the broader semiconductor hierarchy, a CAN transceiver is a bus interface IC and belongs to the interface IC category rather than the MCU, memory, or analog-processing families.
The TCAN337GD combines a 3.3-V supply with an operating data rate of up to 5 Mbps. Its 120 mV receiver hysteresis supports reliable recognition of differential bus states, while the integrated one-driver and one-receiver arrangement provides the basic physical-layer interface required by a CAN node. The SOIC-8 form factor supports conventional surface-mount PCB assembly and provides a practical upgrade path for compact embedded equipment.
The key distinction between TCAN337GD and earlier CAN interface parts is its CAN FD capability. A system using CAN FD can move data at higher bus speeds than conventional CAN while using the same transmitter and receiver arrangement. Designers must still validate the complete network for termination, topology, cable length, transceiver timing, grounding, and the operating limits of every node connected to the bus.
Typical uses include industrial automation controllers, electric-vehicle subsystems, building-control gateways, diagnostic equipment, robotics, and embedded industrial gateways. The 3.3-V supply is particularly useful for systems whose controller operates on a 3.3-V rail. The broad -40°C to +125°C operating-temperature range supports demanding industrial environments, although the complete assembly still requires suitable power delivery, thermal design, and electromagnetic compatibility validation.
For PCB implementation, place the transceiver close to the CAN connector or bus header, connect CANH and CANL according to the selected bus topology, and provide the termination network required by the network design. Keep sensitive return paths compact, use a continuous ground reference, and decouple the 3.3-V supply near the device. The SOIC footprint should be checked against the exact pin assignments and exposed-pad requirements in the manufacturer datasheet before layout release.
This product page consolidates verified manufacturer and distributor information, current sourcing links, interface context, and practical implementation guidance. It also distinguishes confirmed drop-in options from package-ordering codes so engineers do not mistake reel, tube, or shipping-label variations for electrically different replacements.

Типичное применение
TCAN337GD подходит для 6 применениеs: Industrial Automation Controller, Electric Vehicle Subsystem, Building Control Gateway, Robotics Sensor Backbone, Diagnostic and Test Equipment, Embedded Communications Gateway.
Industrial Automation Controller
The TCAN337GD fits an industrial automation controller that must connect a 3.3-V controller or FPGA to a CAN FD field bus. Its confirmed 3 V to 3.6 V supply range supports integration with a 3.3-V rail, while the 5 Mbps CAN FD capability can shorten the data phase compared with conventional CAN operation. The one-driver, one-receiver arrangement provides the basic physical-layer connection for a node. Engineers should calculate termination, fault-current requirements, and propagation-delay margins against the complete bus. The -40°C to +125°C rating is useful for industrial temperature ranges, although enclosure temperature, power quality, EMC behavior, and system isolation must also be validated.
Рекомендуется
Electric Vehicle Subsystem
The TCAN337GD can support a 3.3-V electronic control unit or sensor gateway that communicates over a CAN FD vehicle network. Its 5 Mbps maximum data rate is appropriate for networks designed to use faster CAN FD phases, and the 3 V to 3.6 V operating range simplifies integration with 3.3-V automotive-domain controllers. The broad -40°C to +125°C specification supports applications expected to experience wide temperature variation. However, temperature rating alone does not prove AEC-Q100 qualification, so the exact ordering code and current manufacturer compliance records must be checked before an automotive release.
Рекомендуется
Building Control Gateway
The TCAN337GD is suitable for a building-control gateway that aggregates sensors, actuators, or equipment controllers over a CAN FD backbone. CAN FD support at up to 5 Mbps can benefit nodes that exchange larger diagnostic or control payloads, while the 3.3-V supply range aligns with many embedded building controllers. The transceiver's one-driver and one-receiver configuration maps to a standard network node. Designers should place the device close to the bus connector, preserve a continuous ground reference, apply the calculated termination network, and verify isolation strategy, surge protection, and conducted-emissions requirements for the installation environment.
Рекомендуется
Robotics Sensor Backbone
The TCAN337GD can provide a high-speed CAN FD physical interface for a robot's sensor and actuator backbone. A 5 Mbps data rate supports efficient transfer of motion-control status, sensor data, and diagnostic messages when the network is specifically configured for CAN FD. The 3 V to 3.6 V supply range works with low-voltage embedded controllers, while the 120 mV receiver hysteresis helps distinguish bus states in a multi-node network. Layout should minimize CANH and CANL symmetry violations, keep the transceiver near the connector, and validate bus timing with the longest cable and maximum node population used by the robot.
Рекомендуется
Diagnostic and Test Equipment
The TCAN337GD is appropriate for portable diagnostic equipment or a bench interface that must communicate with a CAN FD-capable controller. Its 3.3-V supply range supports low-voltage test hardware, and the 5 Mbps maximum data rate can accelerate transfers when the target ECU and bus configuration support CAN FD. The half-transceiver arrangement provides one transmitter and one receiver for a compact physical-layer port. Test-equipment developers should account for cable reflections, connector loss, protection requirements, ground differences, and the diagnostic software's supported CAN FD baud rates. Current pin assignments and timing limits must be confirmed in the manufacturer datasheet.
Рекомендуется
Embedded Communications Gateway
The TCAN337GD fits a compact embedded gateway that converts or manages traffic between a CAN FD network and another communications domain. Its 3 V to 3.6 V supply requirement supports a 3.3-V system architecture, and its 5 Mbps CAN FD rating provides a practical interface rate for high-throughput control traffic. The SOIC-8 package supports standard surface-mount assembly without requiring a large transceiver package. Design priorities include uninterrupted ground routing, symmetrical CANH and CANL paths, local supply decoupling, correct termination placement, and verified behavior during bus faults and EMC events. The final gateway should be tested with representative node counts and cable lengths.

Заметки по проектированию
Place the TCAN337GD close to the CAN connector or bus header to minimize the unterminated stub between the transceiver and the external network. Route CANH and CANL together with consistent geometry and similar impedances, avoid crossing or splitting their paths, and connect the transceiver ground to the connector reference ground without introducing unnecessary ground loops.
Decouple the 3.3-V transceiver supply locally and verify that the rail remains within the confirmed 3 V to 3.6 V operating range during bus activity. Place the bypass capacitor near the device supply and ground pins, minimize supply-loop area, and assess whether the source rail requires additional filtering for conducted noise coupled through the CAN cable.
Do not install termination resistors indiscriminately at every node. CAN termination belongs at the physical endpoints defined by the bus topology, and its value must be evaluated with transceiver and cable loading. Also verify the exact 8-pin SOIC pin assignments and logic levels in the manufacturer datasheet rather than relying on a generic CAN-transceiver footprint.
A faster CAN FD data rate can increase sensitivity to reflections, edge degradation, and coupling. Confirm propagation-delay margins using the longest permitted cable, the highest intended bit rate, the planned node count, and the worst-case transceiver timing. Keep external protection and common-mode-choke components out of the differential symmetry unless their exact electrical values are validated in the complete channel.
