Overview
The SN75LVDS84ADGGRG4, produced by Texas Instruments, is a FlatLink™ transmitter integrated circuit designed for high-speed data transmission. This component is particularly suited for applications requiring the transmission of SVGA, XGA, or SXGA data from a controller to a display with very low electromagnetic interference (EMI). It operates on a single 3.3-V supply and consumes less than 1 mW when disabled, making it energy-efficient. The SN75LVDS84ADGGRG4 is packaged in a Thin Shrink Small-Outline Package (TSSOP) with a 20-mil terminal pitch, enhancing its usability in compact designs.
