Overview
The SN65HVD232D is a Controller Area Network (CAN) transceiver designed by Texas Instruments. It is compatible with the ISO 11898-2 High Speed CAN Physical Layer standard and is intended for use in applications that employ the CAN serial communication physical layer. This device is optimized for operation with Texas Instruments' 3.3 V microprocessors, microcontrollers, and digital signal processors (DSPs) that have CAN controllers, or with equivalent protocol controller devices.
The SN65HVD232D is designed to operate in harsh environments and features various protection mechanisms such as cross-wire protection, loss of ground and overvoltage protection, and overtemperature protection. It supports data rates up to 1 Mbps and has a wide common mode range of operation from -2 V to 7 V.
