Product details
Overview
TCAN3414DR from Texas Instruments is a 3.3-V CAN FD transceiver with ultra-low power shutdown mode, ±58 V bus fault protection, and ISO 11898-2:2016 compliance. It supports data rates up to 8 Mbps in simplified networks, delivers symmetrical propagation delays (95–180 ns loop delay), and operates across –40°C to 150°C junction temperature for industrial CAN bus nodes.
For engineers reviewing the TCAN3414DR datasheet, TCAN3414DR pinout, TCAN3414DR application, or TCAN3414DR equivalent, this page provides verified functional specifications, validated standby/shutdown timing behavior, confirmed SOIC-8 and VSON-8 package compatibility, and real-world EMC performance in heterogeneous CAN FD networks.
Technical Context
The TCAN3414DR implements a differential bus driver/receiver pair with integrated TXD-dominant time-out (DTO), thermal shutdown (TSD), and undervoltage detection on VCC (2.75 V rising threshold). Its dual-mode control logic enables transition between normal mode (55 mA typical supply current), low-power standby (10–17 µA), and ultra-low power shutdown (2–5 µA) via dedicated STB and SHDN pins.
Unlike the TCAN3413, the TCAN3414DR omits VIO pin functionality and instead integrates fixed 3.3-V I/O level translation-eliminating external level shifters while maintaining RXD/TXD compatibility with 3.3-V microcontrollers. Bus pins exhibit ±30 V common-mode range and ±10 kV IEC ESD protection, enabling robust operation in electrically noisy factory automation environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - Enables direct connection to 3.3-V system rails without regulator, reducing BOM cost and PCB area. |
| Bus Fault Protection | ±58 V - Sustains transient overvoltage events on CANH/CANL without latch-up or damage, critical for grid infrastructure deployments. |
| Data Rate Support | Up to 8 Mbps - Supports high-speed CAN FD payloads in simplified topologies while maintaining ISO 11898-2:2016 timing margins. |
| Loop Delay (tPROP) | 95–180 ns - Short, symmetrical propagation ensures tight timing margin for 5 Mbps CAN FD arbitration and data phases. |
| Standby Current | 10–17 µA - Enables battery-backed or energy-harvested nodes to maintain remote wake-up readiness over extended periods. |
| Shutdown Current | 2–5 µA - Ultra-low quiescent draw in SHDN mode allows full bus isolation during deep sleep, preserving system-level power budgets. |
| Common-Mode Range | ±30 V - Accommodates ground potential differences across long cable runs in motor drive and industrial transport systems. |
Pinout & Package
TCAN3414DR is available in 8-pin SOIC (D) and 8-pin VSON (DRB) packages. The DRB variant features an exposed thermal pad connected to PCB ground for enhanced thermal dissipation (RΘJB = 23.2 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Digital Input | Transmit data input with 0.3×VCC/0.7×VCC thresholds; integrated pull-up ensures fail-safe dominant state on open-circuit. |
| 2 - GND | Ground Reference | Primary return path for VCC and internal logic; must be low-impedance connection to minimize ground bounce in high-speed switching. |
| 3 - VCC | Supply Input | 3.3-V power rail input with undervoltage lockout (UVLO) at 2.75 V (rising) and 2.65 V (falling) to prevent erratic operation. |
| 4 - RXD | Digital Output | Receive data output with tri-state behavior when unpowered; drives 3.3-V logic with 2 mA sink/source capability. |
| 5 - SHDN | Digital Input | Active-high shutdown enable; high state forces device into ultra-low power mode (2–5 µA), disabling bus drivers and receivers. |
| 6 - CANL | Bus IO | Low-side CAN bus terminal; internally biased to maintain recessive state; withstands ±58 V fault conditions. |
| 7 - CANH | Bus IO | High-side CAN bus terminal; differential pair partner to CANL; supports common-mode range of ±30 V. |
| 8 - STB | Digital Input | Standby mode control; active-high entry into low-power standby (10–17 µA); integrated pull-up enables default wake-up readiness. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power shutdown mode | 2–5 µA ICC enables full bus isolation during system sleep, extending battery life in portable industrial diagnostics tools. |
| ±58 V bus fault protection | Withstands sustained overvoltage on CANH/CANL without latch-up or parameter degradation, eliminating need for external TVS diodes in many designs. |
| IEC 61000-4-2 ±10 kV ESD on bus pins | Meets system-level ESD immunity requirements without additional board-level protection components, simplifying layout and validation. |
| Hot-plug capable operation | Bus and RXD pins remain high-impedance when unpowered, preventing backfeeding or glitches during live insertion/removal of modules. |
| Short and symmetrical propagation delays | 95–180 ns total loop delay with <28 ns pulse skew ensures deterministic timing for 5 Mbps CAN FD bit arbitration and data phase alignment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN337GDR | Single 3.3-V supply, no shutdown mode, lower bus fault rating (±40 V), same SOIC-8/VSON-8 footprint. | Lacks ultra-low power shutdown and reduced bus fault margin; suitable only where continuous operation is guaranteed. | Select TCAN337GDR only if system-level power budget permits constant 55 mA draw and bus environment is protected against >±40 V faults. |
| SN65HVD234DR | Classical CAN only (1 Mbps max), no CAN FD support, no standby/shutdown modes, ±36 V bus fault rating. | Not compatible with CAN FD data phase; cannot support >1 Mbps bit rates required for modern firmware updates or sensor fusion. | Choose SN65HVD234DR only for legacy classical CAN networks where 5 Mbps+ throughput and low-power modes are unnecessary. |
Compared with TCAN3414DR, TCAN337GDR offers identical packaging but sacrifices shutdown capability and bus ruggedness, while SN65HVD234DR lacks CAN FD support entirely-making TCAN3414DR the sole option for new designs requiring 5–8 Mbps operation with ultra-low power states.

FAQ
What is the maximum data rate supported by the TCAN3414DR?
The TCAN3414DR supports classical CAN up to 1 Mbps and CAN FD up to 8 Mbps in simplified networks. At 5 Mbps-the most common CAN FD arbitration/data split point-it maintains full ISO 11898-2:2016 compliance with verified timing margins. Real-world implementation at 8 Mbps requires controlled impedance traces and minimal stub length to preserve signal integrity; the TCAN3414DR's 32–57 ns rise/fall times and <28 ns pulse skew enable this performance.
Does the TCAN3414DR require an external VIO supply?
No, the TCAN3414DR does not require an external VIO supply. Unlike the TCAN3413, it integrates fixed 3.3-V I/O level translation-meaning TXD and RXD operate natively at 3.3-V logic levels without needing a separate VIO rail. This eliminates one external supply and associated decoupling, simplifying design for systems with only a single 3.3-V domain.
How does the TCAN3414DR handle undervoltage conditions?
The TCAN3414DR includes built-in undervoltage lockout (UVLO) on VCC with a rising threshold of 2.75 V and falling threshold of 2.65 V (120 mV hysteresis). When VCC drops below 2.65 V, the device enters a defined fail-safe state: drivers disable, receivers blank, and RXD goes high-impedance. This prevents spurious dominant bus states during brownouts, ensuring network integrity even as host MCU resets.
What is the purpose of the SHDN pin on the TCAN3414DR?
The SHDN pin on the TCAN3414DR is an active-high digital input that places the device into ultra-low power shutdown mode (2–5 µA ICC) when driven high. In this state, all bus drivers and receivers are disabled, CANH/CANL enter high-impedance, and internal biasing is removed-effectively isolating the transceiver from the bus. This mode is essential for battery-powered nodes needing multi-year shelf life or zero-quiescent-current storage.
Can the TCAN3414DR operate without power applied to VCC?
Yes, the TCAN3414DR is hot-plug capable: when VCC = 0 V, CANH, CANL, and RXD present high-impedance states with ≤5 µA leakage, preventing loading of an active bus or backfeeding into the host MCU. TXD remains high-impedance, and STB/SHDN inputs exhibit ≤1 µA off-state leakage. This behavior is explicitly characterized and guaranteed-enabling safe insertion/removal of modules in live CAN networks.
