NXP Semiconductors TJA1124 Quad LIN Commander Transceivers

NXP Semiconductors TJA1124 Quad Local Interconnect Network (LIN) Commander Transceivers provide an interface between a LIN commander protocol controller and the physical bus in a LIN network. Four channels each contain a LIN transceiver and LIN commander termination. The low power consumption TJA1124 components are primarily intended for in-vehicle sub-networks using baud rates up to 20kBd. These automotive sub-networks include ambient mood lighting, body control, HVAC, and park assist. NXP Semiconductors TJA1124 Quad LIN Commander Transceivers offer compliance with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12V LIN), and SAE J2602-1.
