The 74S64PC is an AND-OR-INVERT gate from Texas Instruments — a combinational logic part that performs a sum-of-products function in a single package. For a rework tech or engineer patching a legacy board, this means you can replace a multi-chip AND-OR-INVERT implementation with one DIP, saving board space and reducing propagation delay through fewer interconnects.
Lifecycle and compliance — planning your BOM
The part is RoHS non-compliant, which is typical for older logic families; if your assembly requires RoHS, you will need an exemption or a lead-free alternative.
Package and procurement posture
the 74S64PC is a through-hole device suited for prototyping, repair, or low-volume production where tape-and-reel is unnecessary.
