12 ns propagation delay and 8 macrocells
The GAL16V8Z-12QS is a 12 ns EE PLD from Lattice's GAL® 16V8 series, packing 8 macrocells in a 20-SOIC surface-mount package. That 12 ns propagation delay sets the ceiling on how fast the combinatorial logic can settle — for a 5 V system clocked at 40 MHz, the delay eats about half a cycle, so the path between registered outputs needs to stay short or the timing closure gets tight.
Board-fit and supply rails
The 20-SOIC footprint (0.295-inch body width) is a standard surface-mount package — the 7.50 mm width means it sits on a 1.27 mm pitch, which is a common SOIC layout.
