TCAN334GDR - 3.3V CAN FD Transceiver | Texas Instruments
MPN: TCAN334GDR ✓ ActiveTCAN334GDR Overview
A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into CAN bus differential signals and converts received bus levels back into digital signals for a CAN controller. CAN FD extends the classic CAN frame format with higher supported data rates, allowing a system to transfer larger payloads and improve throughput compared with legacy CAN communication. The TCAN334GDR therefore belongs to the CAN physical-layer transceiver category within interface ICs and is used where a controller needs a standardized, robust connection to a CAN bus.
The verified product data identifies TCAN334GDR as an active, single-driver, single-receiver, 3.3-V CAN FD transceiver. The 8-SOIC package supports compact PCB layouts, while the 3.0 V to 3.6 V operating range is appropriate for systems that already operate from a 3.3 V rail. The -40 °C to 125 °C operating range provides broad temperature capability for embedded automotive, industrial automation, robotics, and communications equipment. The listed receiver hysteresis of 120 mV helps distinguish valid bus levels from noise around the receiver threshold.
Typical applications include a CAN gateway connecting an embedded controller to a vehicle network, a CAN-to-ethernet or CAN-to-USB bridge in industrial equipment, and a distributed actuator or sensor network in a factory automation system. In each case, the transceiver provides the physical layer between the controller and the bus. Designers must provide the controller, bus termination, protection, and application-specific network configuration; the transceiver itself does not replace the CAN protocol controller.
A key design consideration is that the TCAN334GDR is a 3.3-V device, so its TXD, RXD, supply, and signal-level compatibility must match the selected CAN controller and surrounding digital logic. The SOIC footprint also requires attention to thermal performance and copper routing in high-temperature or high-current bus protection implementations. Confirm the complete electrical limits, pin functions, recommended external components, and loopback or fault behavior against the current manufacturer datasheet before final PCB release.
This page summarizes the verified manufacturer and distributor information for TCAN334GDR, including the 3.3-V supply, CAN FD function, 8-SOIC package, temperature range, receiver hysteresis, lifecycle information, sourcing links, and practical design considerations. It is intended to support early design selection and cross-reference work without replacing the manufacturer datasheet for production engineering.

Typical Applications
TCAN334GDR is suitable for 6 applications: Automotive CAN Network Interface, Industrial Automation Controller, CAN-to-USB Gateway, Robotics and Sensor Network, Medical and Diagnostic Equipment, Embedded Communications Equipment.
Automotive CAN Network Interface
The TCAN334GDR fits a 3.3-V embedded CAN interface where a controller requires CAN FD-capable physical-layer signaling. Its verified 3.0 V to 3.6 V supply range matches common low-voltage digital rails, while the -40 °C to 125 °C operating range supports temperature-demanding vehicle and equipment environments. The 8-SOIC package keeps the implementation compact and the listed 120 mV receiver hysteresis supports noise-immunity considerations. The design should confirm TXD/RXD logic compatibility, bus termination, protection, and the exact data-rate limits in the current TI datasheet before release.
Recommended
Industrial Automation Controller
TCAN334GDR is suitable for a factory controller that must connect a CAN-capable microcontroller or industrial processor to a field bus. The verified 3.3-V operation allows sharing a regulated low-voltage rail with compatible digital logic, while the 8-SOIC package supports conventional surface-mount PCB assembly. Its stated -40 °C to 125 °C range covers many industrial environments. Use the transceiver with the appropriate CAN controller, bus termination, isolated or non-isolated network design, and surge-protection components appropriate to the installation environment.
Recommended
CAN-to-USB Gateway
The TCAN334GDR can provide the CAN physical layer for a gateway that bridges a CAN bus to USB, Ethernet, or another embedded communications processor. The single-driver, single-receiver arrangement matches a conventional CAN controller connection, and the 3.3-V supply range is compatible with many gateway platforms. The half-duplex architecture requires the controller and software to manage arbitration and bus access correctly. A practical design must add the required bus termination, protection, grounding strategy, and isolation decision, then validate timing under maximum bus loading.
Recommended
Robotics and Sensor Network
TCAN334GDR is applicable to a distributed robot or sensor network that uses CAN FD communication between a central controller and remote sensing modules. The 8-SOIC footprint supports compact controller boards, and the 3.0 V to 3.6 V operating range can align with a 3.3-V embedded supply. The verified -40 °C to 125 °C range provides useful temperature headroom for industrial robotic equipment. Engineers should budget PCB area for bus protection, maintain short differential routing, provide correct termination at the bus ends, and verify the complete CAN FD timing budget.
Recommended
Medical and Diagnostic Equipment
TCAN334GDR can be evaluated for compact medical or diagnostic equipment that uses a CAN bus for internal module communication. Its 3.3-V supply and 8-SOIC package are useful for space-constrained controller boards, while the broad -40 °C to 125 °C range can assist with non-clinical environmental requirements. Medical designs must separately address applicable electrical-safety, isolation, creepage, and regulatory requirements, none of which are established by the supplied component data. Confirm device qualification, fault behavior, and the complete electrical limits before using it in a safety-related design.
Recommended
Embedded Communications Equipment
The TCAN334GDR is suitable for embedded communications equipment that needs a compact CAN physical layer alongside a host processor. The 3.3-V operating specification supports integration with low-voltage embedded logic, while the 8-SOIC package is compatible with surface-mount manufacturing. The verified receiver hysteresis of 120 mV is a useful bus-noise design parameter, but it must be evaluated together with transceiver timing, termination, propagation delay, and the selected controller. In deployed systems, include reverse-battery, ESD, surge, and transient protection according to the target installation environment.

Design Notes
Place the TCAN334GDR close to the CAN bus connector and the CAN controller to minimize exposed trace length and improve signal integrity. Route the CANH and CANL pair as a tightly coupled differential pair, keep the pair length balanced, and avoid routing it parallel to noisy switching-conductor paths. Use the manufacturer's recommended application circuit and confirm the pin functions in the current datasheet before assigning PCB nets.
Do not treat every 8-pin SOIC CAN transceiver as electrically interchangeable. TCAN334DR and TCAN332DR are comparison candidates only, and the supplied data does not prove identical TXD, RXD, standby, fault, timing, or bus-pin behavior. Before a substitution, compare the official TI datasheets for pinout, supply range, supported data rates, CAN FD capability, dominant-state behavior, and fault handling.
Decouple the 3.3-V supply locally at the transceiver with the capacitance and placement recommended by the manufacturer datasheet. Keep the supply return path short and reference the transceiver ground to the appropriate board-ground plane. If the design includes external transceivers or protection components, account for their current draw so that the local 3.3-V regulator does not become the limiting element during normal CAN bus activity.
Use proper CAN termination at the physical ends of the bus and select protection components with capacitance and current ratings compatible with the intended data rate. Avoid placing large surge-protection capacitance directly beside sensitive differential traces unless the transceiver and protection arrangement has been validated. EMI problems should be investigated across the complete CANH/CANL route, connectors, cable, and grounding rather than isolated only at the IC.
Compliance Information
The supplied verified data does not provide definitive component-level RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. The ETEI comparison page mentions RoHS and REACH as comparison topics, but no extracted values were supplied, so the statuses remain unknown.
