TCAN33x 3.3 V CAN Transceivers

Texas Instruments' TCAN33x family of devices is compatible with the ISO 11898 high-speed controller area network (CAN) physical layer standard. TCAN330 and TCAN332 are specified for data rates up to 1 Mbps. 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 TCAN330 and TCAN332G devices. The devices include many protection features including driver and receiver dominant time out (DTO) providing CAN network robustness. Integrated 12 kV IEC-61000-4-2 ESD Contact Discharge protection eliminates the need of additional components for system level robustness.

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