Overview
The TJA1022T,118 is a dual LIN (Local Interconnect Network) transceiver produced by NXP USA Inc. This component provides the interface between a LIN master/slave protocol controller and the physical bus in a LIN network. It is primarily designed for in-vehicle subnetworks and supports baud rates up to 20 kBd. The TJA1022T,118 is compliant with various LIN standards including LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12 V LIN), and SAE J2602.
