TJA1082TT,118

Specialized Overview

The TJA1082TT,118 is a FlexRay node transceiver compliant with the FlexRay electrical physical layer specification V2.1 Rev. B and incorporating features from V3.0.1. Designed for communication systems operating between 2.5 Mbit/s and 10 Mbit/s, it provides an advanced interface between the protocol controller and the physical bus. The device supports data transfer rates of 2.5 Mbit/s, 5 Mbit/s, and 10 Mbit/s, accommodating a minimum bit time of 60 ns at 400 mV differential voltage. It operates within a supply voltage range of 4.75 V to 5.25 V on pin VCC and includes I/O level adaptation via pin VIO. Packaged in a TSSOP14 plastic thin shrink small outline package (SOT402-1), it is qualified according to AEC-Q100 Grade 1 standards.

Specialized Procurement Notes

Verify component authenticity through authorized NXP distributors. Confirm the ordering suffix matches the required packaging format. Ensure compliance with RoHS directives and check for SVHC declarations prior to integration into automotive designs.

Specialized Selection Notes

Select this transceiver for ECUs that do not require enhanced power management features found in other variants. It is suitable for systems activated by a dedicated wake-up line or ignition switch. Verify compatibility with the host controller's supply voltage levels using the auto I/O level adaptation feature.

Specialized Part Context

This component belongs to the TJA108x series of FlexRay node transceivers manufactured by NXP Semiconductors. It serves as a physical layer interface for FlexRay networks, bridging the gap between digital controllers and the vehicle bus infrastructure while ensuring robust signal integrity.

Specialized Replacement Considerations

The TJA1081BTS,118 is functionally compatible but lacks guaranteed production continuity under the NXP longevity program. Designers should consider the TJA1081G as the recommended replacement part for new designs due to long-term availability assurance.
