Overview
The TCAN337DCNR, produced by Texas Instruments, is a 3.3-V CAN (Controller Area Network) transceiver that complies with the ISO 11898-2 High Speed CAN Physical Layer standard. This device is part of the TCAN33x family, which includes various models such as TCAN330, TCAN332, and TCAN334. The TCAN337 is designed to operate with data rates up to 1 Mbps and is also compatible with the upcoming CAN FD (Flexible Data Rate) standard. It is available in both SOIC-8 and SOT-23 packages, making it suitable for a wide range of applications, including those with space constraints.
