Overview
The TJA1024HG is a quad Local Interconnect Network (LIN) transceiver developed by NXP Semiconductors. It serves as the interface between a LIN master/slave protocol controller and the physical bus in a LIN network. This component is designed primarily for in-vehicle subnetworks, supporting baud rates up to 20 kBd and complying with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602 standards. The TJA1024HG is software-compatible with other NXP LIN transceivers such as the TJA1022, TJA1027, and TJA1029.
