Overview
The SN65HVD233DG4, manufactured by Texas Instruments, is a 3.3-V CAN (Controller Area Network) bus transceiver designed to meet the requirements of the ISO 11898-2 standard. This device is part of the SN65HVD23x family and is specifically tailored for use in harsh industrial and automotive environments. It provides a reliable interface between the CAN controller and the differential CAN bus, supporting data rates up to 1 Mbps.
The SN65HVD233DG4 features advanced protection mechanisms, including bus pins fault protection exceeding ±36 V, ESD protection exceeding ±16 kV HBM, and thermal shutdown protection. It also includes adjustable driver transition times to improve emissions performance and a low-current standby mode to reduce power consumption.
