Overview
The TJA1462ATK/0Z is a CAN (Controller Area Network) transceiver developed by NXP USA Inc. It is part of the TJA146x family, designed to provide an interface between a CAN or CAN FD (Flexible Data rate) protocol controller and the physical two-wire CAN bus. This transceiver is compliant with ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 standards, ensuring full interoperability with high-speed Classical CAN and CAN FD transceivers. The TJA1462ATK/0Z features CAN Signal Improvement Capability (SIC), which significantly reduces signal ringing in the network, enabling reliable CAN FD communication in larger topologies.
