Device identity and technology base
The GAL16V8QS-20LVI is a low-voltage E2CMOS programmable logic device (PLD) from National Semiconductor, part of the GAL16V8 family. It sits in the FPGA / CPLD & Programmable Logic category, serving glue-logic, state-machine, and decode functions where a small, reprogrammable logic array replaces multiple discrete 7400-series parts.
Package and board-fit note
Supplied in Bulk packaging — loose tubes or trays, not tape-and-reel. The GAL16V8QS-20LVI uses the standard 20-pin DIP or SOIC footprint common to the GAL16V8 family; confirm the specific package code suffix (LVI) against the board layout before committing the BOM line.
