TJA1048T - Dual 1Mbit/s CAN Transceiver with Standby | NXP
MPN: TJA1048T ✗ End of LifeTJA1048T Overview
A CAN transceiver is a physical-layer interface IC that converts logic-level controller signals into differential bus signals and converts received bus levels back into logic signals for the host microcontroller. Within the product hierarchy, the TJA1048T is a CAN interface transceiver, a communications interface IC, and an integrated circuit. Its dual-channel architecture allows one controller with two CAN interfaces, or two independent host connections, to share a compact PCB footprint while retaining separate bus connections.
The principal documented features are dual CAN transceivers, high-speed operation up to 1 Mbit/s, differential transmit and receive paths, and a standby mode. According to the NXP TJA1048 manufacturer datasheet, the device provides the physical interface required by a CAN protocol controller. Detailed electrical ratings, supply limits, loop delay, receiver thresholds, bus fault behavior, and thermal limits were not included in the supplied verified data and therefore require confirmation from the manufacturer datasheet before design release.
Technically, each channel bridges the digital domain between a CAN controller and the differential CAN bus. Differential signaling supports noise rejection in automotive environments, while the high-speed rating targets conventional CAN networks operating at 1 Mbit/s. Standby mode provides a defined low-power operating state for systems that need to disable or isolate activity, although the exact input levels, current consumption, and wake behavior must be verified from the complete NXP datasheet.
Typical uses include automotive body electronics, vehicle diagnostic interfaces, engine-control units, industrial automation equipment, robotics, and embedded industrial communications. The dual-channel structure is particularly useful where a controller needs two CAN endpoints without allocating separate single-channel transceivers. Careful review of the datasheet is still essential for termination, common-mode range, bus-exposure, and standby-state requirements.
PCB implementation should preserve the device pinout exactly and place decoupling and bus-path components according to the manufacturer layout guidance. Because this part interfaces with a high-energy shared bus, trace geometry, grounding, surge protection, connector placement, and cable routing can materially affect signal integrity. Do not infer those layout values from general practice; use the verified NXP application information.
This page combines the verified NXP product description, distributor packaging information, datasheet links, lifecycle indication, interface use cases, and verified source trail. It also distinguishes confirmed TJA1048T attributes from parameters that were not supplied, preventing unsupported electrical or cross-reference claims while helping engineers locate the official datasheet and evaluate the product accurately.

Typical Applications
TJA1048T is suitable for 6 applications: Automotive Body Control Module, Vehicle Diagnostic Interface, Industrial Automation Controller, Robotics Communication Hub, Embedded CAN Gateway, Engine or Powertrain Controller.
Automotive Body Control Module
The TJA1048T fits an automotive body control module requiring two high-speed CAN endpoints in a compact 14-pin SO package. Its two differential transceiver channels can connect a CAN controller to physical two-wire CAN buses operating up to 1 Mbit/s, allowing door, lighting, climate, or body-network functions to share one controller. The main engineering benefit is integration: two channels occupy one device package instead of requiring separate single-channel transceivers. Before schematic release, verify the exact pinout, supply limits, common-mode range, transceiver timing, thermal rating, and automotive qualification status in the NXP datasheet, and provide termination and protection appropriate to the vehicle network.
Recommended
Vehicle Diagnostic Interface
The TJA1048T is suitable for a diagnostic gateway that must bridge a host controller to a high-speed CAN physical network. One channel can serve the vehicle's diagnostic CAN connection while the second supports another CAN segment, with differential transmit and receive operation up to 1 Mbit/s. The dual-channel arrangement helps contain wiring and PCB area in space-constrained diagnostic hardware. Engineers should confirm that the selected connector and protection network tolerate the vehicle environment and that the transceiver's verified electrical limits meet the system requirements. The NXP datasheet must also be checked for standby behavior, fault handling, and the precise 14-SO pin assignments before the interface is finalized.
Recommended
Industrial Automation Controller
The TJA1048T can support industrial automation equipment that uses two high-speed CAN connections to coordinate sensors, actuators, and remote machinery. Its dual-channel differential interface supports CAN data rates up to 1 Mbit/s and fits a 14-pin surface-mount package suitable for compact controller boards. The principal advantage is consolidating two physical CAN endpoints while retaining a common device architecture for control and monitoring. Suitability for a particular factory environment cannot be established from the verified data alone, so the design team should verify temperature range, EMC performance, common-mode limits, bus protection, and standby-state current against the NXP datasheet and relevant industrial system requirements.
Recommended
Robotics Communication Hub
The TJA1048T fits a compact robot communication hub that must expose two CAN links to motors, sensors, or remote manipulators. Its two independent high-speed CAN transceiver channels support communication at up to 1 Mbit/s over differential two-wire buses, while the 14-SO package preserves board area in mobile or embedded robotic platforms. The transceiver handles the physical signaling layer between a CAN-capable host controller and the bus; arbitration, message formatting, fault management, and higher-level safety functions remain the controller's responsibility. Before integrating it near motors or noisy power stages, verify the electrical limits, thermal conditions, layout guidance, bus termination, and protection strategy directly from the manufacturer documentation.
Recommended
Embedded CAN Gateway
The TJA1048T is appropriate for an embedded gateway that translates between a host processor and two CAN segments. Its dual-channel design allows separate bus connections without requiring two transceiver packages, and differential signaling provides a physical interface intended for reliable high-speed operation up to 1 Mbit/s. This arrangement is useful in industrial gateways, test equipment, and service adapters where the controller must manage communication on more than one CAN endpoint. Design validation should include review of the 14-SO land pattern, standby-state requirements, supply decoupling, termination placement, common-mode behavior, and any surge or ESD protection. Exact timing and electrical ratings should be obtained from the official NXP TJA1048 datasheet rather than inferred.
Recommended
Engine or Powertrain Controller
The TJA1048T can be evaluated for engine or powertrain control units that exchange high-speed CAN data with sensors, actuators, and other vehicle controllers. Two differential CAN channels support communication up to 1 Mbit/s while limiting the number of physical transceiver packages on a densely populated control board. Because the verified source identifies the device for automotive high-speed CAN, it aligns functionally with vehicle networking, but qualification for a specific powertrain environment must not be assumed. Engineers should confirm the exact temperature rating, EMC and ESD characteristics, bus-fault behavior, supply limits, and AEC-Q100 status from controlled NXP documentation before using the TJA1048T in a safety-relevant production design.

Key Differentiators
- Two CAN physical-layer channels in one package (vs Single-channel CAN transceiver)

- Integrated low-activity control state (vs Transceiver without Standby mode)
- Compact 14-pin surface-mount implementation (vs Larger multi-component CAN interface)
Design Notes
Use the official NXP TJA1048 datasheet land pattern and pin assignments without modification. Place the device close to its CAN connector and termination network to minimize exposed bus-trace length, then route CANH and CANH as a closely coupled differential pair with uninterrupted return-path reference. The verified data confirms a 14-SO package but does not provide dimensions or a land pattern, so those values must not be inferred from a generic SOIC footprint.
Do not treat a same-package transceiver as a drop-in replacement without comparing every pin and electrical characteristic. A candidate must preserve the 14-SO footprint, CAN channel functions, differential logic behavior, supply requirements, Standby-mode implementation, and operation up to 1 Mbit/s. The supplied cross-reference search produced no verified substitutes, so any sourcing proposal should be checked against both the original and candidate manufacturer datasheets before schematic approval.
Plan CAN bus protection and grounding with the complete vehicle or industrial network in mind. Protection components should be selected only after checking the transceiver's verified common-mode range, bus-fault limits, and ESD ratings; the supplied data does not state those values. Keep switching converters, high-current actuators, and connectors away from the differential pair where practical, and follow the NXP application guidance for reference-plane continuity and termination placement.
Confirm the actual supply range, quiescent current, standby current, and transmit-state dissipation from the complete NXP TJA1048 datasheet before designing the power tree. Because two CAN channels can operate in different states, worst-case supply demand should be evaluated across normal receive, transmit, fault, and Standby conditions. Add local high-frequency bypass and bulk capacitance according to the manufacturer's guidance, while checking that each rail remains within the device's verified limits.
Compliance Information
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is recorded as not_applicable because this metadata field concerns the commercial TJA1048T designation and no qualification claim was supplied; do not interpret this as proof that the device lacks automotive qualification.
