That propagation delay sets the floor for your address-to-output valid window — if your bus cycle time is 50 ns, this part leaves 35 ns for the rest of the path. It runs on a single 5V supply, so it mates directly with 5V TTL/CMOS buses without level translation. ## 10 macrocells — right-sized for glue logic consolidation Ten macrocells cover a handful of 74-series logic functions or a small state machine. Each macrocell can be configured as registered or combinatorial, with programmable output polarity. The 22V10 architecture is well-known — any legacy GAL/PAL design ported to this part reuses the same JEDEC fuse-map concepts, though the programming algorithm differs. The 28-PLCC package with J-leads fits standard 28-pin PLCC sockets or direct solder pads. The J-lead profile gives better mechanical compliance than a gull-wing on boards subject to thermal cycling, which matters in industrial or telecom environments where the 5V rail is still in service.","metaTitle":"Microchip ATF22V10C-15JU EE PLD, 15 ns, 10 macrocells","metaDescription":"Microchip ATF22V10C-15JU EE PLD, 15 ns propagation delay, 10 macrocells, 5V supply, 28-PLCC (J-Lead).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["FPGA / CPLD & Programmable Logic"],"specifications":{"Mfr":"Microchip Technology","Speed":"15 ns","Series":"22V10","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"28-LCC (J-Lead)","Product Status":"Active","Voltage - Input":"5V","lifecycle_stage":"eol_hot","Programmable Type":"EE PLD","Base Product Number":"ATF22V10","Number of Macrocells":"10","Supplier Device Package":"28-PLCC (11.51x11.51)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5ae1a1706088582335c7a2d9d815b287.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATF22V10C-15JU/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the ATF22V10C-15JU?","answer":"Within the same 22V10 family, the ATF22V10C-10JU offers a faster 10 ns propagation delay while maintaining the same 28-PLCC footprint, 5V supply, and 10-macrocell architecture. The trade-off is speed grade — the -10JU suits tighter timing budgets, the -15JU is the cost-optimised choice for 50 ns or slower bus cycles."},{"question":"What is the ATF22V10C-15JU used for?","answer":"It is an EE PLD — electrically erasable programmable logic device — used to replace multiple 74-series logic ICs (address decoders, state machines, bus interface logic) in 5V systems.
