The TCAN33x family of devices is compatible with the ISO 11898 High Speed CAN (Controller Area Network) Physical Layer standard. TCAN330, TCAN332, TCAN334 and TCAN337 are specified for data rates up to 1Mbps. Pending the release of the updated version of ISO 11898-2 including CAN FD, additional timing parameters defining loop delay symmetry are specified for the TCAN330G, TCAN332G, TCAN334G and TCAN337G devices. The devices include many protection features including driver and receiver Dominant Time Out (DTO) providing CAN network robustness. Integrated 12kV IEC-61000-4-2 ESD Contact Discharge protection eliminates the need of additional components for system level robustness.

The use of single 3.3V supply enables the transceivers to directly interface with 3.3V CAN controllers/MCUs. In addition, these devices are fully compatible with other 5V CAN transceivers on the same bus.

These devices have excellent EMC performance due to matched Dominant and Recessive Common Modes. Ultra low power Shutdown and Standby modes make these devices attractive for battery powered applications.

This family of devices is available in standard 8-pin SOIC packages for drop-in compatibility and in small SOT-23 packages for space-constrained applications.
