The Texas Instruments SN65LVDS84AQDGG is a 4-channel LVDS line driver in the FlatLink™ family, designed to serialize and drive parallel data over a low-voltage differential pair. It is a pure driver — 4 drivers, 0 receivers — so it handles the transmit side of a point-to-point or multidrop LVDS link.
AEC-Q100 and 125°C — why that matters for the BOM
If the board sits in an engine bay, behind a dashboard in direct sunlight, or near a hot power stage, the 125°C ceiling gives the thermal margin a commercial 85°C part lacks. The AEC-Q100 flow also means the part has passed extended reliability tests — pre-conditioning, high-temperature operating life, temperature cycling — so it is the right choice for any production run where field-return cost outweighs the per-unit premium.
48-TSSOP — footprint and mounting
Housed in a 48-TFSOP (0.240", 6.10mm width) package, also referred to as 48-TSSOP. It is a surface-mount, fine-pitch package — standard for this pin count. The 0.65mm pitch means the PCB layout needs careful trace routing and a soldermask-defined pad.
