Overview
The TJA1443AT/0Z is a high-speed Controller Area Network (CAN) and CAN Flexible Data Rate (CAN FD) transceiver developed and manufactured by NXP USA Inc. This component is part of the TJA144x family and is designed to provide an interface between a CAN or CAN FD protocol controller and the physical two-wire CAN bus. It is fully compliant with ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 standards, ensuring interoperability with high-speed Classical CAN and CAN FD transceivers.
The TJA1443AT/0Z is intended as a simple replacement for existing high-speed CAN and CAN FD transceivers, such as the TJA1043, offering pin compatibility to avoid changes in hardware and software design. This makes it an ideal choice for retrofitting into existing applications.
