Lattice Semiconductor has marked the GAL16V8D-15LP as obsolete.
8 macrocells, 15 ns propagation delay — what it means for the BOM
The GAL16V8D-15LP is an EE PLD from the GAL®16V8 series, offering 8 macrocells with a maximum propagation delay (tpd) of 15 ns. This delay sets the ceiling for registered output toggling — at 15 ns the part supports clock rates up to roughly 66 MHz in a typical glue-logic application, though the actual system speed depends on the external routing and load capacitance. The 8 macrocells each can be configured as combinational or registered outputs, making this a fit for address decoding, state machines, or bus-interface logic where a handful of PAL/GAL equations replace discrete 7400-series logic.
20-DIP through-hole — board-fit and supply rail
Housed in a 20-pin DIP (0.300", 7.62mm body width) with through-hole mounting, the GAL16V8D-15LP fits legacy PCB layouts and prototyping boards. The supplier device package is 20-PDIP. Operating temperature is specified for 0°C to 75°C, the commercial grade, so it is suited for indoor equipment and benchtop environments rather than extended-temperature industrial or automotive zones.
