Overview
The TCAN334GDCNR is a high-speed 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 is designed for applications requiring robust and reliable CAN communication, particularly in automotive, industrial automation, and other high-reliability environments. The TCAN334GDCNR operates on a single 3.3-V supply, making it compatible with 3.3-V CAN controllers and microcontrollers, and it also supports coexistence with 5-V CAN transceivers on the same bus.
