Product details

10 ns PLD for legacy glue-logic — what the speed grade buys you

The ATF16V8B-10PC is a 10 ns electrically erasable PLD from Microchip's 16V8 series, packing 8 macrocells in a 20-pin DIP package that runs on a single 5V supply. The 10 ns propagation delay means combinatorial outputs settle within 10 ns of the input transition.

Through-hole DIP: rework-friendly, pinout-clear

The 20-pin DIP (0.300" width) is a through-hole package — the leads are easy to probe, the pin 1 notch is unambiguous, and the part survives multiple hot-air cycles without pad lift if you keep the nozzle at 300°C and preheat the board to 100°C. The 5V-only supply means no level translation on the I/O banks, but it also means this part won't drop into a 3.3V or 1.8V core logic board without a regulator and level shifters.

No official replacement part is recorded on the lifecycle notice; the closest functional match is a pin-compatible 16V8 variant (e.g., ATF16V8B-10PU), but these may also face obsolescence or differ in speed grade.

Frequently asked questions

Is ATF16V8B-10PC obsolete?

Yes, Microchip lists the ATF16V8B-10PC as obsolete. There is no open last-time-buy window. Sourcing is limited to surplus/new-old-stock inventory through independent channels.

What is the replacement for ATF16V8B-10PC?

No official replacement is recorded on the lifecycle notice. Pin-compatible 16V8 family parts (e.g., ATF16V8B-15PC or ATF16V8B-10PU) may function as drop-in substitutes, but verify speed grade and availability — they may also face obsolescence.

Can ATF16V8B-10PC be programmed with a standard programmer?

Yes, as an EE PLD, the ATF16V8B-10PC is electrically erasable and programmable with standard device programmers that support the 16V8 architecture (e.g., Xeltek, Data I/O, or TL866-series). JEDEC fuse-map files are compatible across the 16V8 family.

What is the difference between ATF16V8B-10PC and ATF16V8B-15PC?

The primary difference is speed grade: the ATF16V8B-10PC has a 10 ns propagation delay, while the ATF16V8B-15PC is rated at 15 ns. Both are 8-macrocell EE PLDs in the same 20-DIP package with 5V supply. The 10 ns part offers tighter timing margin for faster logic paths.
