It operates from a single 5V supply and is housed in a 20-pin DIP (0.300\" body width) — the same footprint as the industry-standard 20L8/PALCE16V8. The 10 ns propagation delay (tPD) sets the timing budget for address decoding, chip-select generation, and state-machine logic. In a system with a 50 MHz clock (20 ns period), a 10 ns PLD leaves only 10 ns for the rest of the path — so this part is best suited for sub-50 MHz designs or for non-critical combinatorial paths where the extra margin is welcome. If your bus runs faster, you'll want a 7.5 ns or 5 ns variant in the same family. ## EE reprogrammability and the 8-macrocell ceiling Being electrically erasable (EE PLD), this chip can be reprogrammed in-circuit or on a programmer without a UV eraser — a real advantage during prototyping and field updates. The 8 macrocells can each be configured as registered or combinatorial outputs, giving you up to 8 flip-flops or 8 sum-of-products terms. That's enough for a 3-to-8 decoder, a small state machine, or a handful of address comparators, but not for a full 16-bit counter or a complex sequencer. Microchip lists the ATF16V8BQ-10PC as obsolete. If you are designing a new board, consider the ATF16V8B-10PU (the lead-free, still-active PLCC/SOIC variant) or a CPLD from the ATF150x family for a drop-in logic upgrade.","metaTitle":"ATF16V8BQ-10PC 16V8 EE PLD, 10 ns, 8 Macrocells, 20-DIP","metaDescription":"ATF16V8BQ-10PC is a 5V EE PLD from Microchip's 16V8 series with 10 ns propagation delay and 8 macrocells in a 20-pin DIP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["FPGA / CPLD & Programmable Logic"],"specifications":{"Mfr":"Microchip Technology","Speed":"10 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":"ATF16V8B","Number of Macrocells":"8","Supplier Device Package":"20-PDIP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7e7967a4b40ed27e1bf71d0cb9df3c42.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATF16V8BQ-10PC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for ATF16V8BQ-10PC?","answer":"Microchip has not published a direct pin-compatible successor for this specific DIP variant. For new designs, consider the ATF16V8B-10PU (same logic, lead-free, available in PLCC/SOIC) or move to a CPLD like the ATF1502AS for more macrocells and faster speeds.

If your board uses a DIP socket, the ATF16V8B-10PU will not fit without an adapter.
