TJA1042AT/3/0Z

Drivers, Receivers, Transceivers Overview

The TJA1042AT/3/0Z is a high-speed CAN transceiver from NXP Semiconductors designed for automotive applications. It interfaces between a CAN protocol controller and the physical two-wire bus, supporting data rates up to 5 Mb/s in CAN FD fast phase. The device operates on a supply voltage of 4.5 V to 5.5 V with a maximum operating temperature of +150 °C. It features an SOIC-8 package and includes ESD protection rated at 8 kV. The component supports standby mode with bus wake-up capability and offers ideal passive behavior when power is off.

Drivers, Receivers, Transceivers Feature Summary

• Compliant with ISO 11898-2:2016 and SAE J2284 standards
• Supports low-current standby mode with bus wake-up
• Provides direct interfacing with 3.3 V to 5 V microcontrollers via VIO pin

Drivers, Receivers, Transceivers Applications

• High-speed CAN networks in 12 V and 24 V automotive systems
• Nodes requiring low-power standby modes with wake-up capability
• CAN FD applications requiring reliable communication at 5 Mbit/s

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Check the product lifecycle status as some variants may be marked as Not Recommended for New Designs (NRND). Ensure the selected part number matches the required voltage interface and packaging format for your specific design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this variant if the application requires a standard SOIC-8 package and direct compatibility with 3.3 V or 5 V logic levels. Consider the TJA1042B or TJA1042C variants if shorter propagation delay is necessary for larger network topologies. Verify that the system environment meets the specified operating temperature range and that the 5.5 V maximum supply voltage aligns with the vehicle's power architecture.

Drivers, Receivers, Transceivers Part Context

This component belongs to the third generation of NXP high-speed CAN transceivers, succeeding earlier models like the TJA1040. It is part of the broader TJA1042 family, which includes variants optimized for different propagation delays and package styles. The TJA1042 series is widely used in automotive electronics where robust EMC performance and low standby current are critical requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1042T/3 is a functional equivalent within the same family. For improved EMC performance in 12 V systems, consider the TJA1044 or TJA1442 as alternatives. Ensure any replacement maintains the same package footprint and voltage interface compatibility.
