Overview
The TJA1448ATK/0Z, produced by NXP USA Inc., is a dual high-speed CAN (Controller Area Network) transceiver designed for automotive and industrial applications. It is part of the TJA144x family, which offers advanced features for CAN and CAN FD (Flexible Data Rate) communication. This component is intended as a simple replacement for dual high-speed Classical CAN and CAN FD transceivers, such as the TJA1059 from NXP. It supports data bit rates up to 5 Mbit/s for CAN FD and is compliant with various industry standards including ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5.
