The TJA1057 is part of the Mantis family of high-speed CAN transceivers. It provides an interface between a
controller area network (CAN) protocol controller and the physical two-wire CAN bus.
The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential
transmit and receive capability to (a microcontroller with) a CAN protocol controller.
The TJA1057 offers a feature set optimized for 12 V automotive applications, with significant improvements over
first- and second-generation CAN transceivers from NXP, such as the TJA1050, and excellent electro magnetic
compatibility (EMC) performance.
The TJA1057 also displays ideal passive behavior to the CAN bus when the supply voltage is off.
