Overview
The SN65LVDS391DR is a quad differential line driver from Texas Instruments, designed to implement the electrical characteristics of low-voltage differential signaling (LVDS). This component is part of a family that includes 4, 8, and 16 line drivers, all of which meet or exceed the requirements of the ANSI EIA/TIA-644 standard. The SN65LVDS391DR is optimized for high-speed signaling rates up to 630 Mbps with very low electromagnetic interference (EMI). It operates with a typical output voltage of 350 mV into a 100-Ω load, making it suitable for applications requiring low power consumption and high switching speeds.
