TJA1057GTKZ - High-Speed CAN Transceiver | NXP
MPN： TJA1057GTKZ ✓ 啟用中TJA1057GTKZ 概覽
A CAN transceiver is an interface IC that connects a CAN protocol controller, normally implemented in a microcontroller, to the physical two-wire CAN bus. Its transmitter converts controller logic into the differential CANH and CANL bus signals, while its receiver converts those differential signals back into logic levels for the controller. The TJA1057GTKZ belongs to the NXP Mantis family of high-speed CAN transceivers designed for automotive applications.
Key verified features include one CAN driver, one CAN receiver, half-duplex communication, 300 mV receiver hysteresis, and a regulated 5 V supply range of 4.75 V to 5.25 V. The wide -40 °C to +150 °C operating range supports demanding industrial and automotive environments. Its 8-HVSON package provides a compact 3 x 3 mm surface-mount footprint for space-constrained electronic control units.
The TJA1057GTKZ provides the physical-layer interface required by a Controller Area Network controller. Differential signaling improves common-mode noise tolerance on the bus, while receiver hysteresis helps distinguish a valid logic transition from noise near the decision threshold. Half-duplex operation means the transmitter and receiver share the same physical CAN interface in accordance with the CAN bus architecture.
Typical applications include automotive CAN networks, electronic control units, body-control modules, powertrain controllers, industrial vehicle communications, and embedded systems that connect a microcontroller or another CAN controller to a two-wire bus. Its small package also suits compact control boards where connector area and routing space are limited.
Designers should verify CANH, CANL, ground, supply, and logic-interface connections against the current NXP datasheet and the selected controller's I/O levels. The 5 V supply must remain within 4.75 V to 5.25 V. Exact data-rate, loopback, bus-fault, and absolute-maximum ratings were not included in the retrieved source data and must be confirmed in the manufacturer documentation.
This product page consolidates verified manufacturer and distributor information, practical application guidance, pricing references, and strict drop-in alternative screening. It distinguishes documented TJA1057GTKZ characteristics from unverified generic substitutes so engineers can make a safer, footprint-conscious sourcing decision.

典型應用
TJA1057GTKZ 適用於 6 應用s: Automotive Electronic Control Units, Body and Chassis Control Modules, Industrial Vehicle CAN Networks, Embedded CAN Communications, Powertrain and Chassis Controllers, Compact CAN Gateway Equipment.
Automotive Electronic Control Units
The TJA1057GTKZ fits automotive electronic control units that require a high-speed CAN physical layer between a CAN-capable microcontroller and a vehicle network. Its one-driver, one-receiver arrangement supports half-duplex bus operation, while the verified -40 °C to +150 °C range covers many demanding vehicle environments. The compact 8-HVSON package is 3 x 3 mm, reducing PCB area compared with larger transceivers. Designers must verify logic compatibility, CAN termination, fault behavior, and the complete pin configuration against the current NXP datasheet before layout release.
推薦
Body and Chassis Control Modules
The TJA1057GTKZ is appropriate for compact body and chassis control modules that exchange diagnostic and control data over a two-wire CAN bus. Its half-duplex one-driver, one-receiver configuration maps directly to the CAN physical layer, and the 300 mV receiver hysteresis provides a defined transition region between bus states. The 3 x 3 mm HVSON footprint is especially valuable where connector access and routing space are constrained. Production designers should also review bus-fault, thermal, and absolute-maximum details that were not included in the retrieved snippets.
推薦
Industrial Vehicle CAN Networks
The TJA1057GTKZ can support CAN communication in industrial vehicles, mobile equipment, and factory transport systems where high-speed controller-area networking links sensors, drives, or operator modules. Its verified 4.75 V to 5.25 V supply range supports regulated 5 V systems, and the -40 °C to +150 °C operating range provides broad environmental headroom. The half-duplex interface suits the shared two-wire CAN topology. Before deployment, verify the supported CAN data rate, standby and fault modes, bus termination, and protection requirements directly in the manufacturer datasheet.
推薦
Embedded CAN Communications
The TJA1057GTKZ is suitable for embedded systems in which a microcontroller or dedicated CAN controller needs to communicate with a remote bus. The device provides the differential transmitter and receiver needed to bridge logic-level CAN-controller signals and the physical CANH and CANL bus. Its half-duplex organization and 300 mV receiver hysteresis align with conventional CAN bus behavior, while the small package supports compact control hardware. Firmware and hardware teams should confirm pin mapping, controller I/O voltage, timing budget, and wake or standby requirements during component selection.
推薦
Powertrain and Chassis Controllers
The TJA1057GTKZ can be evaluated for powertrain or chassis controller networks requiring a compact, high-speed CAN physical interface. Its one transmitter, one receiver, and half-duplex operation provide the core physical-layer functions, while the -40 °C to +150 °C rating is relevant to temperature-variable vehicle environments. The 3 x 3 mm package reduces PCB area without changing the bus topology. Qualification still requires checking maximum data rate, propagation delay, bus-fault behavior, EMC layout guidance, and AEC-Q100 status in the latest controlled NXP documentation.
推薦
Compact CAN Gateway Equipment
The TJA1057GTKZ fits compact CAN gateway equipment intended to bridge or monitor a high-speed CAN network. Its small 8-HVSON 3 x 3 mm package leaves more board area for processing, power management, and connectors. The verified 4.75 V to 5.25 V operating range supports a regulated 5 V rail, and the single transmitter and receiver implement the standard half-duplex physical interface. Engineering review should include bus common-mode range, termination placement, ESD protection, grounding, and the maximum data rate, none of which were quantified in the supplied search extracts.

主要差異化特點
- Compact verified CAN transceiver footprint (對比TJA1057CT)
- Wide specified operating-temperature range (對比TJA1057BT)
- Automotive-oriented high-speed CAN interface (對比TJA1057CT)
設計說明
Route CANH and CANL as a closely coupled differential pair, minimize stub branches, and place the 120-ohm termination only at the physical ends of the bus. Keep the transceiver return path connected to the controller and transceiver ground references with a short, low-impedance path. Verify the exact CANH, CANL, VCC, GND, and logic-pin assignments against the NXP package drawing before releasing artwork because the supplied source snippets did not expose a complete verified pin list.
Supply the TJA1057GTKZ from a regulated 5 V rail that remains between 4.75 V and 5.25 V over temperature and transient conditions. Place the required local supply and return-plane connections close to the device, and account for the transceiver's load current together with CAN bus current in the power budget. The retrieved data did not provide verified quiescent or transmitter-current values, so those limits must be taken from the manufacturer datasheet before selecting regulators or bulk capacitance.
Do not treat a functionally similar CAN transceiver as a drop-in replacement solely because its protocol matches. Confirm package dimensions, exposed-pad requirements, pin names, logic thresholds, VIO behavior, timing, fault modes, and data-rate limits independently. The supplied cross-reference data identifies TJA1057CT and TJA1057BT as functionally similar except for VIO-related voltage levels, but it does not verify the same 8-HVSON 3 x 3 mm footprint required for PCB reuse.
Evaluate thermal performance at the highest expected ambient temperature, CAN load activity, supply voltage, and board copper area. The component is specified for operation from -40 °C to +150 °C, but that rating does not replace a junction-temperature calculation for every PCB. Because the retrieved snippets do not include power dissipation, thermal resistance, or lead-dependency data, use the current NXP datasheet and perform a board-level thermal validation before production release.
合規資訊
The supplied verified snippets identify an automotive-oriented active product but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred.
