Single Channel LIN PHY with INH, Wake Input and 1.8 V VIO support. Can be used as both LIN commander and responder

The TJA1421 is the interface between the Local Interconnect Network (LIN) commander/responder protocol controller and the physical bus. It is primarily intended for in-vehicle subnetworks using baud rates up to 20 kBd and is compliant with LIN 2.x, Society of Automotive Engineers (SAE) J2602 and International Organization for Standardization (ISO) 17987-4:2016 (12 V). The TJA1421 is pin-to-pin compatible with the TJA1021. Not only supporting all functions of TJA1021, TJA1421 also has optimized electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance according to the latest International Electrotechnical Commission (IEC) and SAE standards, tighter responder termination to support more LIN responder (>15) nodes in the same network, 1.8 V voltage input/output (VIO) to support high-end microcontroller unit (MCU) and MCU time-out fail-safe feature to minimize the power consumption.
