TJA1042TK/3,118
Overview
The TJA1042TK/3 is a high-speed CAN transceiver that provides an interface between a Controller Area Network protocol controller and the physical two-wire CAN bus. It is specifically designed for high-speed CAN applications in the automotive and industrial sectors, offering CAN FD capability with data rates up to 5Mbps. This variant includes a Vio pin for direct level-shifting, allowing it to interface seamlessly with microcontrollers powered by 3V to 5V supplies.
Why Choose This Part
The device features extremely low electromagnetic emissions and high immunity (EMI), reducing the need for external filtering. It provides excellent ESD protection up to plus or minus 8kV on bus pins and is robust against transients and high voltages up to plus or minus 58V. The HVSON8 package offers a small 3x3mm footprint while maintaining superior thermal performance for high-temperature environments up to 150 degrees Celsius.
Applications
Key Specifications
Getting Started
To evaluate this transceiver, ensure the Vcc pin is supplied with 4.5V to 5.5V and connect the Vio pin to your microcontroller's I/O voltage level. When designing the PCB, place a 100nF decoupling capacitor close to the supply pins and implement standard 60-ohm termination at both ends of the CAN bus. Use the STB pin to control the transition between normal operating mode and the 5uA low-power Standby mode.
