Product Introduction

Overview

The SN65HVD251DR is a high-speed CAN (Controller Area Network) transceiver produced by Texas Instruments. This device is designed to interface a single-ended CAN controller with the differential CAN bus, adhering to the ISO 11898 standard. It is optimized for operation in harsh environments, offering robust protection against cross-wire, overvoltage, and loss of ground up to ±36 V. The transceiver supports signaling rates up to 1 Mbps and features thermal shutdown protection, glitch-free power-up and power-down, and low-current standby mode.
