The 74BCT827BSPC is a 10-bit bus driver from Texas Instruments in a PDIP24 through-hole package, supplied in bulk (tube or tray). As a BiCMOS bus driver, it buffers and drives heavily loaded backplane or memory-array lines where the fan-out of a standard logic gate would degrade signal integrity — the 10-bit width matches a byte-plus-two-controls bus architecture common in 8/16-bit processor systems.
Package and board-fit note — PDIP24 in a through-hole world
The PDIP24 footprint is a 0.100-inch (2.54 mm) pitch, 0.300-inch (7.62 mm) row spacing — the standard 24-pin DIP layout that has been in production since the 1970s. It fits legacy wire-wrap boards, proto-boards, and plated-through-hole PCBs without a footprint change. Bulk packaging means the parts ship in anti-static tubes or trays, not tape-and-reel. For a manual-insertion line or a rework bench this is fine; for a high-speed auto-insertion line you would need to transfer to tube feeders or request a different packaging option from TI (if available).
