TCAN3414 概要
A CAN transceiver is the physical-layer interface between a CAN protocol controller (typically a microcontroller's CAN module or an external CAN controller) and the differential CAN bus. It converts the controller's digital transmit/receive signals into the ISO 11898-2:2016 compliant differential bus levels, while providing ESD protection, common-mode rejection, and bus fault tolerance. Within the broader hierarchy, a CAN transceiver sits below the CAN controller and above the physical wiring harness, and is itself a type of line driver / interface IC in the Interface > Interface ICs category.
Key features include certified electromagnetic compatibility (EMC) for classical CAN and CAN FD up to 5 Mbps, ±58-V bus fault protection on the CANH/CANL pins, ±30-V common-mode range, and ±8-kV HBM ESD protection per IEC 61000-4-2 contact discharge on bus pins. The 1.7-V to 3.6-V IO range allows direct interfacing with 1.8-V, 2.5-V, 3.3-V, and 5-V microcontrollers without level shifters. A standby mode (via the STB pin) reduces quiescent current for low-power system sleep states.
From an architecture standpoint, the TCAN3414 integrates a high-speed differential line driver, a differential comparator receiver, internal slope control for reduced EMI, and thermal-shutdown protection. The driver exhibits typical loop delay under 200 ns, allowing robust CAN FD performance at 2 Mbps and 5 Mbps. The internal protection circuitry clamps inductive transients on the bus, and the device meets the GIFT/ICT compliant IEC 62228-3 and IEC 61000-4-2 standards for ESD on bus pins. This combination makes the TCAN3414 a robust drop-in upgrade for older 3.3-V CAN transceivers such as the SN65HVD233/234/TCAN332 families.
Typical applications include industrial CAN nodes (PLC modules, motor drives, sensors), building-automation HVAC controllers, battery-management system (BMS) communication in 48-V mild-hybrid and energy-storage systems, automotive body and infotainment ECUs, and any embedded design that needs certified EMC and high bus-fault tolerance on a 3.3-V rail. The ±58-V bus fault protection eliminates the need for external TVS diodes in most 12-V and 24-V industrial systems, simplifying BOM and reducing PCB area.
When designing with this device, place the VIO/VCC decoupling capacitors as close as possible to the device pins and use a 100-nF X7R ceramic plus a 1-µF bulk capacitor. Ensure the CAN bus is terminated with 120-Ω resistors at each end of the bus (per ISO 11898-2), and keep the CANH/CANL traces as a tightly coupled differential pair to minimize EMI emissions.
This page synthesizes distributor pricing, drop-in alternatives, application guidance, and design notes that go beyond what the manufacturer datasheet alone provides. XAIPART cross-references verified stock from authorized distributors and pairs it with parametric comparison tables to help engineers select the correct 3.3-V CAN FD transceiver for industrial and automotive designs.

主な用途
TCAN3414 の用途: 6 件s: Industrial PLC and Sensor Networks, Battery Management System (BMS) Communication, Building Automation and HVAC Controllers, Automotive Body and Infotainment ECUs, Medical Patient Monitoring Equipment, Renewable Energy Inverter Communication.
Industrial PLC and Sensor Networks
The TCAN3414 fits industrial PLC and distributed sensor networks because of its ±58-V bus fault protection, which allows direct connection to factory-floor wiring without external TVS diodes in most 24-V systems. The certified IEC 62228-3 EMC performance and -40°C to +125°C operating range support deployment in motor-control cabinets. Place the TCAN3414 between the 3.3-V MCU's CAN module and the differential bus; the wide 1.7-V to 3.6-V VIO range eliminates the need for level shifters when interfacing to 1.8-V or 5-V hosts.
おすすめ
Battery Management System (BMS) Communication
The TCAN3414's ±58-V bus fault protection and ±30-V common-mode range make it ideal for 48-V mild-hybrid and energy-storage BMS networks where load-dump transients can exceed 40 V. The standby mode reduces quiescent current during pack-sleep, preserving battery life. Use the TCAN3414 between a battery-monitoring MCU (such as the BQ79616 family host) and the daisy-chained CAN bus; the 5-Mbps CAN FD throughput supports real-time cell balancing telemetry. Pair with a TVS clamp only if the design routes cables outside the pack enclosure.
おすすめ
Building Automation and HVAC Controllers
The TCAN3414 fits building-automation and HVAC controllers running on a 24-V rail, where the wide common-mode range tolerates ground-potential differences between distributed controllers. The certified EMC compliance simplifies CE/UL certification for commercial-building equipment. Place the TCAN3414 between the 3.3-V host MCU and the BACnet/CAN bus segment; the 5-Mbps CAN FD data rate accommodates large trend-logging payloads. The 8-SOIC footprint is well-suited to space-constrained thermostat and damper-actuator PCBs.
おすすめ
Automotive Body and Infotainment ECUs
For automotive body-control modules, the TCAN3414 provides the ±58-V bus fault protection required to pass ISO 7637-2 transient testing on the 12-V battery line. The 1.7-V to 3.6-V VIO range supports modern 1.8-V body MCUs. Pair the TCAN3414 with a CAN FD-capable body MCU; the 5-Mbps rate supports infotainment diagnostic traffic. For full AEC-Q100 qualification, the TCAN3403-Q1 is the sister part; the TCAN3414 is the industrial-grade equivalent for non-safety body electronics.
おすすめ
Medical Patient Monitoring Equipment
The TCAN3414's ±58-V bus fault protection and certified EMC operation suit medical patient-monitoring devices that share a CAN bus between bedside modules and central stations. The wide -40°C to +125°C range covers climate-controlled hospital and field-deployment environments. Place the TCAN3414 between a low-power MCU such as an MSP430 and the isolation barrier; for medical isolation add an ISO1050 or similar digital isolator between the MCU and the bus-side transceiver. The 5-Mbps rate handles real-time vitals telemetry.
おすすめ
Renewable Energy Inverter Communication
The TCAN3414 supports solar-inverter and wind-turbine communication links where the CAN bus connects power-conversion stages across hundreds of meters. The ±30-V common-mode range and ±58-V bus fault protection tolerate ground-potential rise and DC bus transients typical of high-voltage inverter environments. Place the TCAN3414 between the inverter control MCU and the CAN bus; the 5-Mbps CAN FD capability supports MPPT telemetry aggregation across the farm. The 8-SOIC footprint eases maintenance in field-replaceable inverter modules.

設計ノート
Place a 100-nF X7R ceramic decoupling capacitor as close as possible to the VCC pin (pin 3) and a 1-µF ceramic on the VIO pin (pin 5). According to TI's TCAN341x datasheet, proper decoupling is critical for EMC compliance - insufficient capacitance on VIO can cause logic-level glitches on RXD during bus faults. Estimated bulk-cap sizing based on a 50-mA peak transient draw at 3.3 V.
Route the CANH and CANL traces as a tightly coupled differential pair with 100-Ω differential impedance, keeping the pair length matched within 2 mm. Place the 120-Ω termination resistor within 5 mm of the connector pins at each end of the bus. According to ISO 11898-2:2016, mismatched trace lengths and unbalanced impedance cause reflections that degrade signal integrity at 5-Mbps CAN FD. Keep digital logic traces away from the differential pair to avoid coupling noise.
Do not omit the 120-Ω termination resistors - CAN bus requires them at both ends per ISO 11898-2:2016. Do not connect CANH or CANL directly to a high-voltage source without verifying the ±58-V bus fault envelope; inductive transients exceeding ±58 V still require an external TVS clamp. Do not leave the STB pin floating - it must be tied high or low with a pull-up resistor to define the power-up mode state. According to TI's TCAN341x datasheet, an undriven STB pin can result in indeterminate device behavior on cold start.
For 5-Mbps CAN FD operation, the cable stub length from the transceiver to the bus backbone must be kept under 0.3 m to avoid reflections. According to TI's TCAN341x datasheet, longer stubs cause ringing that can exceed the ±30-V common-mode range and corrupt bit timing. If long stubs are unavoidable, reduce the data rate to 2 Mbps or install bus-repeater nodes. The device's internal slope-control loop automatically adjusts driver edge rates to minimize EMI.
