What the SN74AS2623N is and where it fits
The SN74AS2623N is a bus transceiver from Texas Instruments' AS logic family, designed for bidirectional data transfer between two independent buses. It handles the line driving and receiving in backplane or cable interconnect applications where the bus needs to be isolated or buffered.
RoHS non-compliance — what it means for your assembly line
This part is RoHS non-compliant, which means it contains lead (Pb) in the solder finish or material composition. If your board house runs a lead-free reflow profile, this part won't play well — you'll need a waiver or a segregated line. For legacy repair or military/aerospace builds where leaded solder is still acceptable, that's not a problem; just flag it in the BOM so procurement doesn't accidentally send it to a RoHS-only line.
Sourcing reality for the SN74AS2623N
Because the SN74AS2623N is active and RoHS non-compliant, it's not a high-volume commodity part that every distributor stocks on the shelf. If you're filling a BOM line for a repair or a small production run, this is the kind of part where a quick RFQ call gets you a straight answer on whether it's sitting in someone's inventory or needs a factory order.
Package and handling note for the bench
That's fine for the rework bench or low-volume assembly, but if your pick-and-place line expects reels, plan on hand-placing this one or asking the distributor to transfer to tape if they offer that service. The Bulk format also means no moisture-sensitive label (MSL is typically Level 1 for DIP packages), so no bake-out needed before soldering as long as the parts haven't been sitting in a humid warehouse for years.
