8-macrocell EE PLD in a legacy DIP footprint
The Lattice GAL16V8D-7LP is an electrically erasable programmable logic device (EE PLD) from the GAL®16V8 series, packing 8 macrocells in a 20-pin DIP package. This through-hole 20-PDIP (0.300", 7.62mm) footprint was the standard for PAL/GAL socket replacement in 1990s-era control boards, telecom line cards, and industrial logic circuits where a handful of sum-of-products equations replaced multiple 74-series logic gates.
No pin-compatible successor is recorded from the original manufacturer for this exact speed grade and package variant; the closest functional replacement within the GAL16V8 family may require a board revision or a different speed bin.
Board-fit considerations for the 20-DIP footprint
As an EE PLD, the device can be erased and reprogrammed in-circuit (typically 100 erase/write cycles per macrocell), though the 7 ns propagation delay (tpd) of this -7 speed grade sets the ceiling for registered output toggle rates — budget the 7 ns into the clock-to-output timing path for any synchronous logic.
