Overview
The SN65HVD231 is a 3.3-V CAN (Controller Area Network) transceiver produced by Texas Instruments. This device is designed to be compatible with the ISO 11898-2 High Speed CAN Physical Layer standard and is intended for use in harsh environments. It interfaces the single-ended host CAN protocol controller with the differential CAN bus, making it suitable for industrial, building automation, and automotive applications. The SN65HVD231 is a low power replacement for the PCA82C250 footprint and features various protection mechanisms such as cross wire protection, loss of ground, overvoltage protection, and overtemperature protection.
