TJA1081TS,112

Specialized Overview

The TJA1081TS,112 is a FlexRay node transceiver compliant with specification V2.1 Rev. A and incorporating V3.0.1 features. It supports data transfer rates from 1 Mbit/s to 10 Mbit/s and operates within a battery supply voltage (VBAT) range of 6.5 V to 60 V. The device functions with a +5 V supply (VCC) between 4.75 V and 5.25 V, and an I/O supply (VIO) ranging from 2.2 V to 5.25 V. Packaged in an SSOP-16 format, it provides differential transmit and receive capabilities for automotive networks.

Specialized Feature Summary

• Enhanced low-power modes optimized for ECUs permanently connected to the battery
• Comprehensive system performance monitoring via dedicated error and status information
• High ElectroMagnetic Immunity through a differential receiver with wide common-mode range
• Robust protection against ESD pulses and automotive transient voltages

Specialized Applications

• Time-triggered communication systems
• FlexRay network nodes requiring permanent battery connection
• Automotive electronic control units (ECUs)

Specialized Procurement Notes

Verify component authenticity by cross-referencing the ordering code TJA1081TS,112 with official NXP documentation. Confirm package type matches SSOP-16 specifications. Ensure compliance with RoHS directives before integration into production assemblies.

Specialized Selection Notes

Select this component for applications requiring FlexRay physical layer compliance up to 10 Mbit/s. Verify that the host controller supports the required mode control signals. Ensure power supply rails align with the specified operating ranges for VBAT, VCC, and VIO.

Specialized Part Context

This part belongs to the TJA1081 series of FlexRay node transceivers manufactured by NXP Semiconductors. It serves as an interface between protocol controllers and the physical bus in FlexRay networks, supporting both linear passive and active star topologies.

Specialized Replacement Considerations

The TJA1081B is functionally compatible but lacks guaranteed production continuity. For new designs, consider the TJA1081G or TJA1081GL, which offer enhanced low-power management for battery-connected ECUs.
