TJR1442ATK/S1Z

Drivers, Receivers, Transceivers Overview

The TJR1442ATK/S1Z is a high-speed CAN transceiver from the TJR144x family, designed for automotive applications. It provides an interface between a CAN or CAN FD protocol controller and the physical two-wire bus, compliant with ISO 11898-2:2016 and SAE J2284 standards. The device supports data rates up to 5 Mbit/s in both Classical CAN and CAN FD fast phases. It operates within a VCC supply voltage range of 4.5 V to 5.5 V and features Normal and Standby modes. The component is qualified to AEC-Q100 Grade 0, supporting operation at ambient temperatures up to 150 °C. It utilizes an HVSON-8 package (3.0 mm x 3.0 mm) and includes ESD protection rated at 8 kV.

Drivers, Receivers, Transceivers Feature Summary

• Supports Standard CAN and CAN FD data bit rates up to 5 Mbit/s
• Features low-power Standby mode with host and bus wake-up capability
• Provides high ESD handling capability on bus pins
• Includes undervoltage detection and defined fail-safe behavior

Drivers, Receivers, Transceivers Applications

• Automotive CAN network nodes requiring high reliability
• CAN FD systems operating at flexible data rates up to 5 Mbit/s
• Applications needing direct interfacing with 3.3 V or 5 V microcontrollers via VIO pin

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix TK/S1Z against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compatibility with AEC-Q100 Grade 0 requirements for your target thermal environment. Confirm that the HVSON-8 footprint matches your PCB design guidelines for thermal dissipation and automated optical inspection.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when AEC-Q100 Grade 0 qualification is required for operation up to 150 °C ambient temperature. The 'A' designation indicates the presence of the VIO pin for I/O level adaptation, making it suitable for mixed-voltage microcontroller interfaces. Compare against the TJA1442 if a lower temperature grade (Grade 1, up to 125 °C) suffices for your application constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TJR144x family of high-speed CAN transceivers. It serves as a pin-compatible replacement for legacy devices like the TJA1042 or TJA1044GT, allowing for easy retrofitting into existing hardware designs without software modifications. The family emphasizes gap-free operation and predictable fail-safe behavior under varying supply voltage conditions.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1442ATK/S1Z is a compatible alternative within the same product family but operates at a lower temperature grade (up to 125 °C). Verify that the reduced thermal rating meets your system's maximum ambient temperature requirements before substitution.
