Overview
The SN65LVDS84AQDGGR is a FlatLink™ low-voltage differential signal (LVDS) transmitter produced by Texas Instruments. This component is designed for high-speed data transmission and is particularly suited for applications requiring low power consumption and minimal external components. The device integrates three 7-bit parallel-load serial-out shift registers and four LVDS line drivers, enabling the transmission of 21 bits of single-ended LVTTL data over three balanced-pair conductors. It operates from a single 3.3-V supply and is characterized by its ultralow power consumption, making it an efficient choice for various high-speed data transmission needs.
