Low-voltage E2CMOS PLD for field-replaceable logic
The National Semiconductor GAL16V8QS-15QVC is a Low Voltage E2CMOS PLD — a programmable logic device that replaces multiple discrete logic gates with a single chip you can reprogram in-system or swap on site. It sits in the FPGA / CPLD & Programmable Logic category, meaning it handles glue logic, address decoding, or state-machine tasks that would otherwise eat board space with 74-series parts.
Bulk package and board-fit considerations
Supplied in Bulk packaging — not tape-and-reel, so it arrives in tubes or trays. For a repair tech swapping a socketed PLD on site, this means the part comes loose in the kit without the handling fuss of a cut tape. The E2CMOS architecture retains the programmed logic without a battery — no backup cell needed on the board, and the device wakes up configured on power-up.
