TCAN330DCNR - 3.3V 1Mbps CAN Transceiver | Texas Instruments
MPN： TCAN330DCNR ✓ 啟用中TCAN330DCNR 概覽
A CAN transceiver is an interface integrated circuit that connects a host controller's logic-level transmit and receive signals to the physical CAN bus. In the CAN communication hierarchy, it sits between a CAN controller or microcontroller and the differential bus wiring. This physical-layer role converts logic signals into bus-compatible states, receives bus activity, and provides bus-fault, short-circuit, ESD, undervoltage, and thermal-shutdown protection.
The TCAN330DCNR combines a compact SOT-23-8 footprint with a maximum CAN data rate of 1Mbps. Its listed 3V to 3.6V operating range supports low-voltage systems that do not use a conventional 5V CAN transceiver supply. Additional protection features include undervoltage protection, thermal shutdown protection, bus-fault protection, and short-circuit protection, reducing the amount of external protection required around the CAN bus interface.
The device also supports low-power shutdown and standby operation, making it attractive for battery-powered and energy-conscious equipment. A silent mode provides another low-activity operating option, while TXD dominant-timeout behavior helps determine whether the transmitter should remain active when the controller does not provide expected dominant-state signaling. These operating modes allow a system designer to balance bus availability, current consumption, and fault response.
Typical uses include industrial sensor nodes, battery-operated condition-monitoring equipment, compact industrial controllers, building automation endpoints, and embedded automotive or transportation accessories operating from a 3.3V rail. In each case, the transceiver provides the physical interface while a CAN-capable microcontroller or communication controller handles frame construction, arbitration, error management, and higher-level protocols.
PCB implementation requires attention to the small SOT-23-8 footprint, the pin-specific bus and logic connections, and the separation of sensitive logic traces from the CAN bus conductors. Use the manufacturer datasheet pin-description table to verify every connection before layout. The CAN bus interface also benefits from a protected connector path, controlled return-path geometry, and an appropriate common-mode network appropriate to the installed bus topology.
This product page combines the exact ordering information, operating limits, package details, protection features, application guidance, comparison parameters, and selection considerations needed to evaluate TCAN330DCNR. It also clarifies which verified substitutions are genuinely pin-compatible and prevents package or supply-format differences from being mistaken for functional drop-in replacements.

典型應用
TCAN330DCNR 適用於 6 應用s: Battery-Powered CAN Sensor Node, Industrial Condition-Monitoring Terminal, Building Automation Controller, Compact Automotive Accessory Module, Robotics Motor and Sensor Hub, Battery Energy Storage Monitor.
Battery-Powered CAN Sensor Node
The TCAN330DCNR fits compact battery-powered sensor nodes because it operates from a 3V to 3.6V supply and supports low-power shutdown and standby modes. Its listed 20uA low-power specification can help a designer reduce current draw when the node does not need continuous CAN communication. The device remains available for a 1Mbps CAN bus, while TXD dominant timeout, undervoltage protection, and thermal shutdown protection help the controller manage abnormal operating states. A 3.3V CAN-capable MCU can manage protocol traffic while the TCAN330DCNR provides the physical bus interface.
推薦
Industrial Condition-Monitoring Terminal
The TCAN330DCNR is appropriate for industrial condition-monitoring equipment that distributes sensor readings over a CAN bus. Its 1Mbps maximum data rate supports higher-speed embedded CAN traffic, while the compact 8-pin SOT-23 DCN package preserves board area in distributed monitoring devices. The -40°C to +125°C operating range covers demanding industrial environments, and the listed bus-fault and short-circuit protections support robust interface behavior. Pair it with a CAN-capable MCU and protected connector path.
推薦
Building Automation Controller
The TCAN330DCNR can connect a compact building-automation controller to a CAN-based building network. The 3.3V supply range suits modern 3.3V embedded systems, while the small SOT-23-8 package supports dense control boards. Shutdown and standby modes help manage energy use in rooms or zones that operate intermittently, and silent mode provides a controlled low-activity state. For reliable operation, the design should add appropriate bus protection and verify logic thresholds and timing against the selected controller.
推薦
Compact Automotive Accessory Module
The TCAN330DCNR is suitable for space-constrained 3.3V accessory modules that communicate over CAN. Its 1Mbps rate, -40°C to +125°C operating range, and listed ESD, undervoltage, bus-fault, short-circuit, and thermal-shutdown protections make it a strong interface candidate. A compact SOT-23-8 footprint allows placement near a connector, but the complete module still requires appropriate automotive qualification review, bus transients, power-supply design, and system-level fault verification.
推薦
Robotics Motor and Sensor Hub
The TCAN330DCNR can serve as the CAN physical interface for a robot sensor hub or motor-control coordination node. A 1Mbps bus rate supports time-efficient communication between distributed modules, while shutdown and standby modes help manage system energy when subsystems are inactive. The compact SOT-23-8 package is useful in crowded robotics controllers, and the listed bus-fault and short-circuit protections strengthen interface robustness. CAN arbitration remains the responsibility of the host controller.
推薦
Battery Energy Storage Monitor
The TCAN330DCNR fits a battery energy-storage monitor that reports pack measurements to a central controller over CAN. Its 3V to 3.6V operating range aligns with common low-voltage embedded rails, and low-power shutdown and standby support energy-conscious behavior between measurement cycles. At up to 1Mbps, the interface can support responsive status and fault reporting. The implementation should include defined shutdown behavior, appropriate protection for external wiring, and careful separation between CAN bus traces and sensitive measurement circuitry.

主要差異化特點
- Purpose-built for low-voltage CAN nodes (對比Conventional 5V CAN transceivers)
- Compact 8-pin SOT-23 implementation (對比8-pin SOIC package options)
- Multiple low-activity operating modes (對比Always-active CAN interface designs)
設計說明
Place the TCAN330DCNR near the CAN connector or protected bus entry point, while keeping the CANH and CANL route short and as closely coupled as practical. Avoid routing these conductors beneath digital clocks, switching-regulator nodes, or sensitive analog inputs. Use the manufacturer pin-description table and DCN package drawing to confirm every terminal. A compact SOT-23-8 land pattern requires careful courtyard clearance so adjacent components do not interfere with soldering or inspection.
Design the 3.3V supply rail to remain within the TCAN330DCNR's 3V to 3.6V operating range under startup, load, and fault conditions. Place the required local supply and return capacitors close to the device pins according to the manufacturer application guidance. Account for the listed 60mA supply-current figure when sizing the regulator, wiring, and thermal path. Decide whether low-power, standby, or silent operation is required by the system power-state strategy.
Do not treat a shared SOT-23 outline or similar orderable suffix as proof of pin compatibility. Before substituting another CAN transceiver, compare the DCN terminal mapping, 3.3V supply requirements, logic thresholds, CAN timing, common-mode range, and enable functions. Also confirm the bus connector and external protection design, since transceiver-level ESD or fault protection does not remove the need for a suitable system-level interface and power architecture.
Keep CAN bus conductors away from high-current switching paths and maintain a continuous return reference beneath the interface. If the PCB crosses unrelated noisy nets, use a short ground reference alongside the crossing where the layout rules permit. External protection near the connector can reduce stress reaching the transceiver, but its capacitance and clamping behavior should be checked against the required 1Mbps signaling and CAN bus parameters before use.
