TJA1448ATK/S1Z

Drivers, Receivers, Transceivers Overview

The TJA1448ATK/S1Z is a dual high-speed CAN transceiver with Standby mode from the NXP TJA144x family. It provides an interface between a CAN or CAN FD protocol controller and the physical two-wire bus, supporting data rates up to 5 Mbit/s in the CAN FD fast phase. The device operates within a VCC supply voltage range of 4.5 V to 5.5 V and features independent control for two transceivers in a single HVSON14 package. It includes undervoltage detection, internal biasing for fail-safe behavior, and overtemperature protection. The component complies with ISO 11898-2:2016 and SAE J2284 standards.

Drivers, Receivers, Transceivers Feature Summary

• Dual channel architecture with independent Normal and Standby mode control
• Low-power management with host and bus wake-up capability
• High ESD handling capability on bus pins
• Predictable and fail-safe behavior under undervoltage conditions

Drivers, Receivers, Transceivers Applications

• Automotive Controller Area Network (CAN) systems
• CAN Flexible Data-rate (FD) communication interfaces
• Industrial automation networks requiring robust signal integrity

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and variant features. Ensure compatibility with system voltage requirements and thermal design constraints before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel solution with low standby current is required. Verify that the HVSON14 package fits the PCB layout and that the microcontroller interface matches the I/O levels supported by the specific variant selected.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TJA144x series, designed as a replacement for older dual high-speed CAN transceivers like the TJA1059. It offers pin compatibility to simplify hardware upgrades while providing enhanced features such as CAN FD support and improved electromagnetic immunity.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1448A/B variants are designed as direct replacements for the TJA1059 due to pin compatibility.
