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 3Vto5V
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.
