TJA1042 in NXP TJA CAN Transceivers Family
The TJA1042 is a family of high-speed CAN transceivers manufactured by NXP Semiconductors, designed to provide an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. Engineered primarily for the automotive industry, these devices offer advanced electromagnetic compatibility (EMC) and high electrostatic discharge (ESD) protection. They are fully compliant with ISO 11898-2:2016 and SAE J2284-1 through SAE J2284-5, facilitating robust communication in harsh electrical environments typical of modern vehicle architectures.
Variants in This Sub-Family
Variants within the TJA1042 sub-family differ primarily based on the functionality of the VIO pin and the integration of specific protection features. The TJA1042/3 variant includes a VIO pin for direct interfacing with microcontrollers operating at 3.3V or 5V, while the standard TJA1042 lacks this pin. Additionally, certain versions are optimized for specific timing parameters or package types like SO8 or HVSON8 to meet space-constrained PCB requirements.
