Logic function and production status
The 54S64FM is an AND-OR-INVERT gate from Texas Instruments, a logic building block that combines AND and OR functions into a single inverting output stage — useful for glue logic in processor or memory interface designs where you need to collapse a few product-of-sums terms without an extra package.
Supplied in Bulk package — no reel or tape carrier, so expect loose tubes or trays depending on the distributor's handling. The Bulk format suits prototype builds or low-volume production where pick-and-place tape feed is not required.
