Overview
The SN65LVDS84AQDGG is a FlatLink™ low-voltage differential signal (LVDS) transmitter produced by Texas Instruments. This device is designed to transmit high-speed data with minimal electromagnetic interference (EMI), making it suitable for various display applications such as SVGA, XGA, and SXGA data transmission from a controller to a display.
The SN65LVDS84AQDGG is part of the SN65LVDS84A family, which includes ultralow-power 3.3-V CMOS versions of the SN75LVDS84. It operates from a single 3.3-V supply and consumes significantly less power compared to its predecessors, with a typical power consumption of 89 mW.
This component is packaged in a Thin Shrink Small-Outline Package (TSSOP) with 48 pins and is characterized for operation over the full Automotive temperature range of -40°C to 125°C, making it ideal for high-reliability automotive applications.
