TJA1057T/1Z

TJA1057T/1Z is a high-speed CAN transceiver. 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. It offers a feature set optimized for 12V automotive applications, with significant improvements over first- and second-generation CAN transceivers from NXP, such as the TJA1050, and excellent ElectroMagnetic Compatibility (EMC) performance. The TJA1057 also displays ideal passive behaviour to the CAN bus when the supply voltage is off. Variants with a VIO pin can be interfaced directly with microcontrollers with supply voltages from 3.3V to 5V.
