That is fast enough for glue logic, address decoding, and state machines in legacy 5 V bus systems, but not for high-speed synchronous interfaces above 80 MHz. Eight macrocells, each configurable as registered or combinatorial output, match the standard 20-pin PAL/GAL footprint. The EE PLD technology means the device is electrically erasable and reprogrammable — no UV eraser required, unlike older one-time-programmable PALs. ## 5 V supply — legacy bus compatibility If your board already carries a 5 V rail for other legacy logic, this drops straight in. Board layout is fixed for this footprint — no SMT reflow profile needed. ## Active production — but watch the RoHS flag RoHS non-compliant (lead-bearing solder finish). This is acceptable for military, aerospace, and some industrial applications with RoHS exemptions, but it blocks EU-compliant consumer or medical builds.","metaTitle":"Lattice GAL16V8ZD-15QP EE PLD, 15 ns, 20-DIP","metaDescription":"GAL16V8ZD-15QP from Lattice Semiconductor — 15 ns speed, 8 macrocells, 5V EE PLD in 20-DIP.
