TJA1046V | Dual High-Speed CAN Transceiver | NXP Semiconductors

For best experience this site requires Javascript to be enabled. To enable on your browser, follow our accessibility instructions.

The TJA1046V is a dual high-speed CAN transceiver that provides two interfaces between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN-bus. It is composed of two fully independent TJA1044V transceivers.

The transceivers are designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1046V guarantees robust communication at data rates up to 5 Mbit/s as used in, for example, CAN FD networks. The TJA1046V offers a feature set optimized for 12 V automotive applications and excellent ElectroMagnetic Compatibility (EMC) performance.
