The Texas Instruments SN75LVDS84DGGR is a 4-channel LVDS driver from the FlatLink™ series, designed to serialize and transmit parallel data over low-voltage differential signaling links. It packs four driver outputs with no integrated receivers — a pure transmit-side device — and operates from a single 3V to 3.6V supply, typically a 3.3V rail.
4 drivers, 0 receivers — pure transmit channel
The 4/0 driver/receiver count tells you this is a transmitter only. Each of the four LVDS outputs can drive a point-to-point or multi-drop differential pair, but there is no integrated receiver for bidirectional links. If your design needs a transceiver (both transmit and receive), you would pair this with a separate LVDS receiver like the SN75LVDS82 or look at a transceiver part. For a one-way video data bus from a timing controller to column drivers, the 4-channel transmit-only arrangement is exactly what the FlatLink architecture expects.
3.3V supply and commercial temperature — indoor design fit
No 5V or 1.8V supply needed, which simplifies the power tree.
