That speed puts it in the fast-glue-logic tier: it can decode addresses for a 40 MHz bus without adding a wait state, or generate chip-selects with enough margin that the downstream memory doesn't see a setup-time violation on a cold board at 70 °C. No last-time-buy window remains open through the factory. ## Pin-compatible replacement path The B suffix parts use a different programming algorithm and have slightly different timing characteristics. If you are re-spinning the board anyway, the ATF16V8B is the natural successor — same 8 macrocells, same 5V rail, same 20-PDIP package. For an existing programmed ATF16V8C-7PC, the JEDEC file will need recompilation for the B variant's fuses. ## 20-pin DIP — the socketed legacy footprint The 0.300-inch wide, 7.62 mm body 20-pin DIP is the standard through-hole PLCC-alternative footprint. It fits a 24-pin socket with the outer four positions unused, or a dedicated 20-pin DIP socket.","metaTitle":"ATF16V8C-7PC EE PLD, 7.5 ns, 20-PDIP, Obsolete","metaDescription":"Microchip ATF16V8C-7PC electrically erasable PLD, 8 macrocells, 7.5 ns propagation delay, 5V supply, 20-pin DIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["FPGA / CPLD & Programmable Logic"],"specifications":{"Mfr":"Microchip Technology","Speed":"7.5 ns","Series":"16V8","Package":"Tube","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","Voltage - Input":"5V","lifecycle_stage":"eol_hot","Programmable Type":"EE PLD","Base Product Number":"ATF16V8C","Number of Macrocells":"8","Supplier Device Package":"20-PDIP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7daeacdf2c8da6a7020962928d2f0e6a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATF16V8C-7PC/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for ATF16V8C-7PC?","answer":"The ATF16V8B is the closest pin-compatible successor in the same 16V8 family and 20-pin DIP package, but it requires a JEDEC file recompile — the programming fuses differ.
