The GAL16V8D-15LPN: Quantities are lot-specific and confirmed at RFQ.
8 macrocells, 15 ns tpd — the speed-grade fit
The GAL16V8D-15LPN is an EE PLD from the GAL®16V8 family, offering 8 macrocells with a maximum propagation delay (tpd) of 15 ns. This 15 ns speed grade determines the maximum clock frequency the device can support in a registered configuration — the internal feedback path and output register setup time add to this delay, so the actual system clock is lower than 1/tpd suggests. The commercial temperature grade (0°C to 75°C) limits this variant to controlled indoor environments — not suitable for extended industrial or automotive ambient ranges without thermal margin analysis.
20-DIP through-hole — board integration
Housed in a 20-pin DIP (0.300", 7.62mm) with a through-hole mounting style, the GAL16V8D-15LPN fits standard 0.100-inch pitch prototyping boards and legacy socketed designs. The supplier device package is 20-PDIP. Tube packaging is typical for through-hole PLDs — the tube protects the leads during handling and storage. The EE PLD programmable type means the device is electrically erasable and can be reprogrammed in-system or on a programmer — no UV erasure window is required. This is a mature process node; the programming voltage and algorithm are specific to Lattice's GAL architecture.
