What this ALS bus driver is for
The Texas Instruments SN74ALS667NT3 is an ALS-series bus driver, as described in the listing.
The RoHS non-compliant marking means it contains lead in the solder finish — a factor for designs that must meet RoHS exemption rules or for legacy repair stock that explicitly requires tin-lead terminations for reliability on existing boards.
That typically means the devices ship in tubes or trays. For a pick-and-place line this may require a tube feeder or tray handler; for hand-insertion or rework it is straightforward. Verify with your distributor that the shipping medium matches your floor setup.
