Product details

Obsolete — sourcing via independent channel

The ATF16V8B-10SI is officially obsolete, per the manufacturer's product status. No new production runs are planned. The only supply path is through independent distribution — surplus stock, last-time-buy inventory, or broker-sourced material.

10 ns speed grade — timing margin in glue logic

The 10 ns propagation delay (tPD) is the fast end of the 16V8B speed range. In a 5 V system, this provides combinatorial delay budget between registers.

8 macrocells, 20-SOIC wide body

The 16V8 architecture provides 8 macrocells, each configurable as registered or combinatorial output. The device is programmed as an EE PLD — electrically erasable, reprogrammable. The package is a 20-SOIC with 0.295-inch body width (7.50 mm), which is the wide-body variant.

Frequently asked questions

Is ATF16V8B-10SI obsolete?

Yes, the ATF16V8B-10SI is officially obsolete. No new production is planned. Sourcing is limited to surplus and broker-channel inventory.

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

The only difference is the speed grade: the -10SI has a 10 ns propagation delay, while the -15SI is rated at 15 ns. Both share the same 16V8 architecture, 8 macrocells, 5 V supply, and 20-SOIC wide-body package. The -10SI is the faster bin.
