TJA1042T/1 NXP 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. 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) 2.2 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) 2.3 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
