TJA1042
High-speed CAN transceiver with Standby mode
Rev. 7 — 8 May 2012
Product data sheet
1. General description
The TJA1042 is a high-speed CAN transceiver that 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 (up to 1 Mbit/s) 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
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.
