3 Description

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.
