ALS bus driver in a through-hole bulk package
The SN74ALS29845NT is a Texas Instruments ALS-series bus driver — a 20-pin through-hole part that buffers and drives data onto a shared bus. The bulk tube packaging means it ships loose in a tube, not on a reel, which is the standard for through-hole DIP and wide-body packages that go into socketed or wave-soldered boards.
What the bulk package means on the bench
Bulk tube delivery is the standard format for through-hole DIP packages — it feeds directly into tube handlers for wave soldering or manual insertion. No tape-and-reel fee, no carrier tape waste, and the tubes stack in standard anti-static bins. For a rework tech, the through-hole body means the part lifts clean with a desoldering iron or hot-air station set to 260°C; the tin-lead finish reflows at a lower temperature than SAC305, so the risk of lifted pads on a double-sided board is lower.
Sourcing and availability for the BOM line
Active lifecycle means TI still manufactures the SN74ALS29845NT — no last-time-buy window, no end-of-life clock ticking. For volume procurement, the bulk tube format keeps per-unit cost predictable across the order quantity.
