AND gate, TTL — what this part is
The 54ALS21AW/883 is an AND gate from the TTL logic family, performing the basic Boolean AND function. It is a single-gate device intended for general-purpose logic integration in digital systems where TTL-compatible levels are required.
For procurement, this translates to no imminent end-of-life risk for ongoing designs.
This is a shipping medium, not the device package itself — confirm the actual case style (e.g., DIP, SOIC) from the full datasheet before board layout.
