TJA1441DT/0Z

Drivers, Receivers, Transceivers Overview

The TJA1441DT/0Z is a high-speed CAN transceiver from the TJA144x family, designed for interface between CAN/CAN FD controllers and physical bus lines. It complies with ISO 11898-2:2016 and SAE J2284 standards, supporting data rates up to 5 Mbit/s. The device operates on a single 4.5 V to 5.5 V supply (VCC) and features Normal, Silent, and Off modes. It includes undervoltage detection, TXD dominant time-out, and overtemperature protection. Available in SO8 and HVSON8 packages, it offers ESD protection of ±8 kV and supports operation from -40 °C to +150 °C.

Drivers, Receivers, Transceivers Feature Summary

• Supports Normal, Silent, and controlled Off modes via dedicated input pins
• Provides fail-safe behavior through internal biasing and undervoltage detection
• Includes TXD dominant time-out function to prevent permanent bus blocking
• Offers high ESD handling capability on bus pins

Drivers, Receivers, Transceivers Applications

• Automotive Controller Area Network (CAN) systems
• Industrial control networks requiring high electromagnetic immunity
• Applications needing silent mode for node diagnosis and failure containment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the SO8 package variant when sourcing. Confirm that the '0Z' suffix indicates RoHS compliance and halogen-free status as per NXP specifications. Ensure compatibility with existing PCB footprints for SO8 packages during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select the TJA1441DT/0Z when a dedicated hardware pin is required to switch the transceiver into a low-current Off state, disengaging it from the bus. This variant differs from the TJA1441B by providing an explicit OFF input rather than relying solely on undervoltage conditions for shutdown. It is suitable for designs prioritizing power management through direct microcontroller control of the transceiver state.

Drivers, Receivers, Transceivers Part Context

The TJA1441DT/0Z belongs to the TJA144x family of high-speed CAN transceivers. It serves as a replacement for legacy devices like the TJA1051 or TJA1057, offering pin compatibility while adding modern features such as controlled Off mode. The family supports both Classical CAN and CAN FD protocols at speeds up to 5 Mbit/s.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1441DT/0Z is pin-compatible with the TJA1051 and TJA1057. Designers retrofitting these older components can use the TJA1441DT without hardware changes, provided they utilize the OFF pin appropriately or leave it unconnected if only Normal/Silent modes are needed.
