TJA1057GT/3J Electronic Components

Product Introduction

The TJA1057GT/3J Electronic Components is part of the Mantis family of high-speed CAN transceivers.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 ElectroMagnetic Compatibility (EMC) performance.

A VIO pin on the TJA1057GT(K)/3 variants allows for direct interfacing with 3.3 V and 5 V-supplied microcontrollers.The TJA1057 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5.These features make the TJA1057 an excellent choice for HS-CAN networks that only require basic CAN functionality.
