Overview

The NXP PCA82C250 is an industry-standard CAN transceiver designed for 5 V CAN networks. It serves as an interface between a CAN protocol controller and the physical two-wire CAN bus. This transceiver is fully compliant with the ISO 11898 standard, offering robust and reliable communication in automotive and industrial environments.

Why Choose This Part

Engineers choose the PCA82C250 for its adherence to the ISO 11898 standard, ensuring broad compatibility within existing CAN infrastructure. Its integrated protection against transients, short-circuits, and thermal overload enhances system reliability. The low-current Standby mode and common-mode range for EMI immunity further contribute to its suitability for demanding applications.

Applications

Automotive CAN Networks
Enabling reliable data exchange between ECUs in vehicles for functions like engine management, body control, and infotainment.
Industrial Control Systems
