Overview
The SN65HVD235D is a 3.3-V CAN (Controller Area Network) bus transceiver produced by Texas Instruments. This device is designed to interface between a CAN controller and the differential CAN bus, supporting data rates up to 1 Mbps. It is particularly suited for harsh environments due to its robust protection features, including overvoltage protection up to ±36 V, ESD protection exceeding ±16 kV HBM, and thermal shutdown protection. The transceiver is compliant with the ISO 11898-2 standard and is used in various industrial, automotive, and building automation applications.
