Overview
The SN65LVDS31D is a high-speed differential line driver produced by Texas Instruments. This device implements the electrical characteristics of low-voltage differential signaling (LVDS), which reduces power consumption, increases switching speeds, and allows operation with a 3.3-V supply rail. The SN65LVDS31D is part of a family of LVDS drivers that meet or exceed the requirements of the ANSI TIA/EIA-644 standard.
This quad driver is packaged in a 16-pin SOIC (D) package and is designed for high-speed data transmission applications. It is pin compatible with several other devices, including the AM26LS31, MC3487, and μA9638, making it a versatile choice for various system designs.
