Bus driver identity and package
The SN74AS841ADWR is a bus driver from Texas Instruments' AS series, designed for high-speed data bus buffering and line driving in microprocessor and memory systems. It ships in Bulk packaging, which means the part is supplied in tubes or trays rather than tape-and-reel — a consideration for manual assembly or low-volume production runs where reel feeders aren't needed.
This part is RoHS non-compliant, meaning it contains lead (Pb) above the 0.1 % threshold. That rules it out for new builds requiring RoHS exemption-free compliance, but it is still acceptable for legacy designs, military/aerospace contracts with leaded solder exemptions, or repair stock where the original BOM specified tin-lead finish.
