Product Description

Overview
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 the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007) and the pending updated version of ISO 11898-2:2016. Pending the release of the updated version of ISO11898-2:2016 including CAN FD and SAE J2284-4/5, additional timing parameters defining loop delay symmetry are specified. 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.

## Features
### General
* Fully ISO 11898-2:2003 and ISO 11898-5:2007 compliant
* Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
* Suitable for 12 V and 24 V systems
* Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
* VIO input on TJA1042T/3 and TJA1042TK/3 allows for direct interfacing with 3 V to 5 V microcontrollers
* SPLIT voltage output on TJA1042T for stabilizing the recessive bus level
* Available in SO8 package and leadless HVSON8 package (3.0 mm × 3.0 mm) with improved Automated Optical Inspection (AOI) capability
* Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
* AEC-Q100 qualified
### Predictable and fail-safe behavior
* Very low-current Standby mode with host and bus wake-up capability
* Functional behavior predictable under all supply conditions
* Transceiver disengages from the bus when not powered up (zero load)
* Transmit Data (TXD) dominant time-out function
* Bus-dominant time-out function in Standby mode
* Undervoltage detection on pins VCC and VIO
### Protections
* High ESD handling capability on the bus pins (±8 kV)
* High voltage robustness on CAN pins (±58 V)
* Bus pins protected against transients in automotive environments
* Thermally protected
