Overview
The SN65HVD235-Q1 is a 3.3-V Automotive CAN Bus Transceiver manufactured by Texas Instruments. This device is designed for use in harsh automotive environments and is compatible with the ISO 11898-2 standard, making it interoperable in mixed networks that employ both 5-V and 3.3-V CAN transceivers. It operates from a 3.3-V supply, reducing the need for additional components or a separate supply to power the CAN transceiver and microcontroller. The transceiver features advanced protection mechanisms including crosswire protection, overvoltage protection up to ±36 V, loss-of-ground protection, overtemperature protection, and common-mode transient protection up to ±100 V.
