Overview
The TCAN337GDCNR is a 3.3-V CAN (Controller Area Network) transceiver produced by Texas Instruments. It is part of the TCAN33x family, which is compatible with the ISO 11898 High Speed CAN Physical Layer standard. This device supports data rates up to 5 Mbps with CAN FD (Flexible Data Rate) and is available in both SOIC-8 and SOT-23 packages, making it suitable for a variety of applications, including space-constrained designs. The TCAN337GDCNR features a single 3.3-V supply operation, enabling direct interface with 3.3-V CAN controllers/MCUs, and it is also compatible with other 5-V CAN transceivers on the same bus.
