Product details
Overview
TJA1057T,118 from NXP Semiconductors is a high-speed CAN transceiver designed for automotive HS-CAN networks. It provides differential transmit/receive capability between a CAN protocol controller and the physical two-wire bus, operates at up to 1 Mbit/s, features AEC-Q100 qualification, and supports silent mode for fault containment in 12 V systems.
For engineers reviewing the TJA1057T,118 datasheet, TJA1057T,118 pinout, TJA1057T,118 application, or TJA1057T,118 equivalent, this device delivers ISO 11898-2:2024 compliance, robust EMC performance per IEC TS62228 and SAE J2962-2:2019, undervoltage detection on VCC, and fail-safe bus disengagement when powered down - critical for automotive body control and powertrain communication interfaces.
Technical Context
The TJA1057T implements the CAN physical layer per ISO 11898-2:2024 third edition and SAE J2284-1 to J2284-5, with timing parameters validated for reliable 1 Mbit/s operation. Its block diagram integrates slope-controlled driver, differential receiver, TXD dominant time-out logic, and internal biasing on TXD/S pins.
Unlike VIO-equipped variants (e.g., TJA1057GT/3), the TJA1057T lacks a VIO pin - its TXD, RXD, and S I/O levels are referenced to VCC and compatible with 5 V-tolerant microcontrollers. It exhibits passive bus behavior when VCC = 0 V and includes thermal shutdown at 185 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 1 Mbit/s - meets standard CAN (not CAN FD) timing requirements per ISO 11898-2:2024. |
| Supply Voltage (VCC) | 4.5 V to 5.5 V - optimized for 12 V automotive systems with integrated undervoltage detection (3.5–4.3 V threshold). |
| Bus Voltage Range | CANH/CANL withstand ±42 V - ensures resilience against load dump and jump-start transients. |
| ESD Protection | ±8 kV IEC 61000-4-2 on CANH/CANL - exceeds automotive EMC immunity requirements. |
| Operating Temperature | −40 °C to +150 °C virtual junction temperature - qualified per AEC-Q100 Grade 0 for under-hood applications. |
| Supply Current (Normal Mode) | 2–10 mA recessive / 20–70 mA dominant - enables low-power wake-up and efficient bus arbitration. |
| TXD Time-out | 0.8–6.5 ms - prevents permanent bus dominance due to controller lockup, releasing bus to recessive state. |
Pinout & Package
Package: SO8 (SOT96-1), plastic small outline, 8-lead, 3.9 mm body width, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Digital input | Transmit data from CAN controller; internally pulled up to VCC; triggers dominant time-out if held LOW > 0.8 ms. |
| 2 - GND | Ground reference | Primary ground connection; die supply ground tied to pin and exposed pad (in HVSON8); must be soldered to PCB ground. |
| 3 - VCC | Power supply | 4.5–5.5 V main supply; undervoltage detection disables bus drivers below 3.5 V. |
| 4 - RXD | Digital output | Receives decoded CAN bus data; HIGH = recessive, LOW = dominant; compatible with 5 V-tolerant MCU I/O. |
| 5 - n.c. | Not connected | No internal connection; must remain unconnected - not VIO (absent in TJA1057T variant). |
| 6 - CANL | Analog I/O | Low-side CAN bus line; differential pair with CANH; ±42 V absolute max rating; ESD-protected. |
| 7 - CANH | Analog I/O | High-side CAN bus line; differential pair with CANL; symmetric output voltage (±400 mV Vdom symmetry). |
| 8 - S | Digital input | Silent mode control; HIGH disables transmitter (bus floats recessive), LOW enables full transceiver operation. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2:2024 compliance | Fully compliant physical layer implementation - guarantees interoperability with other HS-CAN nodes in automotive networks. |
| Silent mode with bus release | Pin S HIGH disables driver while preserving receiver function - isolates faulty controllers without disrupting network monitoring. |
| Fail-safe undervoltage response | Automatic bus disengagement (high-ohmic) when VCC drops below 3.5 V - prevents undefined bus states during brownout. |
| Integrated TXD dominant time-out | Hardware timer forces bus recessive after 0.8–6.5 ms of continuous TXD LOW - eliminates software/hardware lockup risks. |
| Passive bus behavior at VCC = 0 V | CANH/CANL present high-impedance state with no leakage current - enables hot-plug compatibility and zero-power bus integrity. |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TJA1055T/3 | Lower ESD rating (±6 kV), no TXD time-out, non-AEC-Q100 qualified; SO8 package only. | Targeted at cost-sensitive industrial CAN networks, not automotive-grade systems. | Select only for non-automotive applications where AEC-Q100 and fail-safe features are unnecessary. |
| MCP2551-I/P | Legacy 5 V-only design; no undervoltage detection; higher ICC (12 mA typical recessive); no Silent mode. | Used in legacy automotive ECUs and industrial PLCs requiring basic ISO 11898-2 compliance. | Choose when backward compatibility with older schematics is required and modern fail-safes are not mandated. |
Compared with TJA1057T,118, the TJA1055T/3 lacks critical automotive safety features like TXD time-out and AEC-Q100 qualification, while the MCP2551-I/P offers no Silent mode or undervoltage protection - making TJA1057T,118 the only option meeting full ISO 11898-2:2024 and ASIL-B support requirements out-of-the-box.

FAQ
What is the maximum data rate supported by the TJA1057T,118?
The TJA1057T,118 supports a maximum data rate of 1 Mbit/s, fully compliant with ISO 11898-2:2024 for high-speed CAN. It is not rated for CAN FD operation - that capability is exclusive to variants with VIO pins (e.g., TJA1057GT/3). The TJA1057T,118's timing parameters, including propagation delay and loop delay symmetry, are specified and validated only up to 1 Mbit/s.
Does the TJA1057T,118 have a VIO pin?
No, the TJA1057T,118 does not have a VIO pin. Pin 5 is marked "n.c." (not connected) in its SO8 pinout. Its TXD, RXD, and S I/O levels are referenced to VCC and designed for direct interface with 5 V-tolerant microcontrollers. For 3.3 V MCU compatibility, use VIO-equipped variants like TJA1057GT/3 instead.
How does Silent mode function on the TJA1057T,118?
When pin S is driven HIGH, the TJA1057T,118 enters Silent mode: the transmitter is disabled and bus lines (CANH/CANL) float to recessive, but the receiver remains fully active - allowing continued monitoring of bus traffic. This prevents a faulty controller from blocking network communication while preserving diagnostic visibility, a key requirement in ASIL-B systems.
Is the TJA1057T,118 AEC-Q100 qualified?
Yes, the TJA1057T,118 is AEC-Q100 qualified per Grade 0 (−40 °C to +150 °C virtual junction temperature), verified by external test houses. This qualification covers thermal cycling, humidity testing, and ESD robustness - confirming suitability for under-hood automotive applications including engine control and EPS systems.
What happens to the CAN bus when VCC is removed from the TJA1057T,118?
With VCC = 0 V, the TJA1057T,118 exhibits ideal passive behavior: CANH and CANL enter a high-impedance, floating state with negligible leakage current (<5 μA). This preserves bus integrity and allows safe hot-plug operation - critical in modular automotive architectures where modules may be powered independently.
