Product details

15 ns EE PLD — 8 macrocells in a 20-PLCC footprint

The Microchip ATF16V8CZ-15JU is an electrically erasable programmable logic device (EE PLD) from the 16V8 family, packing eight macrocells with a 15 ns propagation delay. It operates from a 5 V supply and comes in a 20-lead PLCC with J-bend leads (9x9 mm body). This is the classic 20-pin PLD footprint — same as the original 16V8 series — so it drops into legacy socketed or soldered layouts without a board spin.

The 15 ns speed rating is the pin-to-pin propagation delay (tPD) through the device. In a typical address-decode application, that means the PLD output settles 15 ns after the address inputs stabilise.

The 20-PLCC (J-Lead) package is a surface-mount footprint with the leads tucked under the body. The J-bend gives a smaller footprint than an SOIC but requires a specific solder-paste stencil aperture.

That means it is still in the current portfolio — no last-time-buy notice, no forced redesign for legacy BOM lines.

Frequently asked questions

What is the speed of ATF16V8CZ-15JU?

The listed propagation delay is 15 ns (pin-to-pin, tPD). That is the time from input transition to valid output — the spec that determines whether this PLD fits your logic timing budget.

What is the closest pin-compatible alternative to ATF16V8CZ-15JU in this family?

The ATF16V8B-15JU is a direct pin-compatible alternative within the same 16V8 family and same 20-PLCC package. Both are active 8-macrocell EE PLDs with 15 ns speed at 5 V. The difference is in the internal architecture — the 'CZ' variant includes an extra power-saving feature (CMOS zero-power) that drops standby current versus the 'B' variant. For most logic-replacement jobs, either works in the same socket with the same programming file, but verify the output drive and power-up state in your specific application.
