5 ns pin-to-pin — timing budget for address decode and glue logic
The GAL16V8C-5LP is a 5 ns EE PLD from Lattice's GAL® 16V8 series, offering 8 macrocells in a 20-pin DIP package. The 5 ns propagation delay sets the timing margin for combinatorial decode paths — a 50 MHz address bus needs the output valid before the next clock edge, and this part delivers that headroom without adding wait states. It operates from a 4.75V to 5.25V supply rail, placing it in the legacy 5V-only logic family. The through-hole 20-DIP (0.300", 7.62mm) body is socketable or wave-solderable, and the 20-PDIP footprint matches the industry-standard GAL16V8 pinout — a drop-in replacement for earlier 20-pin PAL/GAL devices in existing boards.
The 5 ns speed grade is the fastest in the GAL16V8C family; if the timing budget allows a 7.5 ns window, the GAL16V8C-7LP (same pinout, same 8 macrocells) is a direct parametric alternative that may offer better supply depth.
