This means TI has flagged it for eventual discontinuation; new designs should not start with this part, and existing production runs need a last-time-buy or a qualified replacement on the roadmap. The official status is NRND, not yet EOL, so the part remains available through independent distribution for ongoing builds while you qualify an alternate.
The DS90LV031ATMTC is a quad LVDS driver from Texas Instruments, delivering four independent differential outputs at a data rate of 400 Mbps per channel. The 4/0 driver/receiver count means this is a pure driver — no receiver on-chip — so it is used in point-to-point or multidrop LVDS links where the receiving end has its own LVDS receiver. The 400 Mbps rate supports common video, clock, and data distribution in industrial imaging, motor-drive feedback, and telecom backplane applications.
16-TSSOP footprint and supply rails
The supply range of 3V to 3.6V aligns with 3.3V nominal rails common in FPGA and SoC systems.
