TJA1042TK

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.

Features and benefits

General
■ Fully ISO 11898-2 and ISO 11898-5 compliant
■ 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 (available in SO8 and very small HVSON8 packages respectively)
■ SPLIT voltage output on TJA1042T for stabilizing the recessive bus level (available in SO8 package only)
■ Available in SO8 and HVSON8 packages
■ 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)

Low-power management

■ 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)

Protections

■ High ESD handling capability on the bus pins
■ Bus pins protected against transients in automotive environments
■ Transmit Data (TXD) dominant time-out function
■ Bus-dominant time-out function in Standby mode
■ Undervoltage detection on pins VCC and VIO
■ Thermally protected
