TJA1021T/20/CM,118

LIN 收发器 LIN 2.1/SAE J2602 transceiver

General description TJA1021T/20/CM

The TJA1021 is the interface between the Local Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN. It is primarily intended for in-vehicle sub-networks using baud rates from 1 kBd up to 20 kBd and is LIN 2.1/SAE J2602 compliant. The TJA1021 is pin-to-pin compatible with the TJA1020 with an improved ElectroStatic Discharge (ESD) specification.
