Overview
The TJA1462AT/0Z, produced by NXP USA Inc., is a high-performance CAN (Controller Area Network) transceiver that belongs to the TJA146x family. This device is designed to provide an interface between a CAN or CAN FD (Flexible Data rate) protocol controller and the physical two-wire CAN bus. It adheres to the CAN physical layer specifications defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, ensuring full interoperability with high-speed Classical CAN and CAN FD transceivers. The TJA1462AT/0Z features CAN Signal Improvement Capability (SIC) as defined in CiA 601-4:2019, which significantly reduces signal ringing in the network, enabling reliable CAN FD communication in larger topologies.
