TJA1042T/3/1 

SOP-8

1. General description The TJA1042 high-speed CAN transceiver 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 TJA1042 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1040. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features: ? Ideal passive behavior to the CAN bus when the supply voltage is off ? A very low-current Standby mode with bus wake-up capability ? TJA1042T/3 and TJA1042TK/3 can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V The TJA1042 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. These features make the TJA1042 an excellent choice for all types of HS-CAN networks, in nodes that require a low-power mode with wake-up capability via the CAN bus. 2. Features and benefits 2.1 General ? ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant ? Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase ?
