CAN Transceivers Family (14 parts in our catalog)

CAN Transceivers are physical layer interface devices designed to convert digital protocol controller signals into differential bus signals, and vice versa. Manufactured by industry leaders such as Texas Instruments, NXP Semiconductors, and onsemi, these components enable robust communication across the Controller Area Network (CAN) bus. They are essential for bridging the gap between low-voltage microcontrollers and the high-voltage, high-noise environments typical of industrial and automotive networking, ensuring reliable data exchange through differential signaling.

Key Features

• High electromagnetic immunity and low electromagnetic emissions
• Wide common-mode input voltage range for ground offset tolerance
• Integrated bus protection including ESD and high-voltage fault protection
• Support for CAN FD data rates up to 5 Mbps or higher

Typical Use Cases

Embedded engineers integrate CAN transceivers primarily in automotive electronic control units (ECUs) for powertrain, body electronics, and advanced driver-assistance systems (ADAS). In these environments, the transceivers handle the physical signaling for critical functions like engine management and sensor fusion. Beyond automotive, they are extensively used in industrial automation for factory floor networking via protocols like CANopen or DeviceNet, where long cable runs and electrical noise are prevalent. They are also standard in building automation for HVAC and elevator control systems, and in medical equipment where high reliability is non-negotiable. The devices are often selected based on their power-down behavior, such as low-power standby modes with remote wake-up capabilities, and their ability to withstand DC battery short circuits or high-voltage transients in harsh operating conditions.
