概要
Description
The SN65HVD257DR is a high-speed CAN (Controller Area Network) transceiver designed by Texas Instruments. It is tailored for use in automotive and industrial applications, providing reliable data communication over harsh environments. This device supports data rates up to 1 Mbps and is compliant with the ISO 11898-2 standard. It features a split-output functionality that allows for improved electromagnetic compatibility (EMC) and reduced radiated emissions, making it suitable for EMI-sensitive applications.
The SN65HVD257DR includes various protective features, such as over-temperature protection, undervoltage lockout, and a dominant time-out function to prevent bus lockup conditions. It operates over a wide voltage range of 4.5V to 5.5V and can tolerate a common-mode voltage range of -12V to 12V, offering robust performance in different operating conditions. Additionally, it supports low-power modes to minimize power consumption, which is essential for applications that require energy efficiency. Its compact SOIC-8 package facilitates easy integration into circuits with limited space.
