25 ns PAL-type PLD — legacy logic glue
The Texas Instruments GAL20V8-25QNC is an electrically erasable programmable logic device (EE PLD) with a 25 ns propagation delay, built on a PAL-type architecture. It sits in the Discrete Semiconductors category, serving as programmable logic for glue-logic consolidation in existing designs.
Active lifecycle, RoHS non-compliant
Texas Instruments lists this part as Active in production. It is RoHS non-compliant — a legacy-chemistry device that does not meet current EU restriction-of-hazardous-substances directives. Designs requiring RoHS exemption or a tin-lead solder process are the natural home for this part.
Bulk package — design-in checklist
Supplied in Bulk format — loose tubes or trays rather than tape-and-reel. This suits low-volume builds, prototyping, or rework where pick-and-place is not the primary assembly method. The 25 ns speed grade sets the maximum system clock frequency; budget the propagation delay into the timing closure for registered outputs.
