Overview
The TJA1024HGZ, produced by NXP USA Inc., is a quad Local Interconnect Network (LIN) transceiver designed for use in in-vehicle subnetworks. This component provides the interface between a LIN leader/follower or master/slave protocol controller and the physical LIN bus. It is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602 standards, making it suitable for a wide range of automotive applications. The TJA1024HGZ features two independent and separated dual LIN transceiver blocks on a single die, each with dedicated supply pins, which enhances its functionality and reliability in automotive communication systems.
