TJA1042T,118

Drivers, Receivers, Transceivers Overview

The TJA1042T,118 is a high-speed CAN transceiver designed for automotive applications. It interfaces between a CAN protocol controller and the physical two-wire bus. Operating with a VCC supply voltage of 4.5V to 5.5V, it supports data rates up to 5 Mbit/s in the CAN FD fast phase. The device operates within a virtual junction temperature range of -40°C to +150°C. Supply current reaches a maximum of 70 mA in normal mode dominant state. It features an SO8 package and includes a SPLIT pin for common-mode stabilization.

Drivers, Receivers, Transceivers Feature Summary

• Implements ISO 11898-2:2016 and SAE J2284 standards for reliable communication
• Features very low-current Standby mode with bus wake-up capability
• Provides ideal passive behavior to the CAN bus when supply voltage is off
• Includes SPLIT output pin on this variant to stabilize recessive bus levels

Drivers, Receivers, Transceivers Applications

• Automotive high-speed CAN networks
• Nodes requiring low-power standby modes with bus wake-up
• 12 V and 24 V system implementations

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and pin configuration. Ensure the component meets AEC-Q100 qualification requirements for your target application environment. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this variant specifically if the design requires the SPLIT pin functionality for stabilizing recessive bus levels in networks with DC leakage. This version differs from VIO variants by having the VIO input internally connected to VCC, making it suitable for direct interfacing with 5 V microcontrollers without external level shifting.

Drivers, Receivers, Transceivers Part Context

The TJA1042 belongs to the third generation of NXP high-speed CAN transceivers. It offers significant improvements over first- and second-generation devices like the TJA1040 regarding electromagnetic compatibility and electrostatic discharge performance. The product line includes variants with either a SPLIT or VIO pin depending on the required interface logic levels.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include TJA1042BT,118 and TJA1042CT,118. Verify that substitute part numbers match the specific pin function (SPLIT vs VIO) required by the circuit design.
