Overview
The SN65HVD233-Q1 is a 3.3-V CAN (Controller Area Network) bus transceiver designed and manufactured by Texas Instruments. This device is specifically qualified for automotive applications and complies with the ISO 11898-2 standard, ensuring interoperability in mixed networks that employ both 5-V and 3.3-V CAN transceivers. It operates from a single 3.3-V supply voltage, making it ideal for systems that use 3.3-V microcontrollers, thereby reducing the need for additional components or a separate supply. The transceiver is built to operate in harsh environments and features various protection mechanisms such as overvoltage protection, thermal shutdown, and common-mode transient protection.
