8-line TTL multiplexer — active and in production
The 54ALS251W/883 is an 8-line input multiplexer implemented in TTL logic, selecting one of eight data sources onto a single output line. Listed as active in production, so this part carries no end-of-life risk for ongoing builds or legacy BOM maintenance.
Package and supply format
Supplied in bulk — loose units rather than tape-and-reel, which suits low-volume assembly, prototyping, or rework benches where pick-and-place feeders are not used.
