15 ns EE PLD in a 24-SOIC footprint
The Microchip ATF22V10B-15SC is an electrically-erasable programmable logic device from the 22V10 family, offering 10 macrocells with a 15 ns propagation delay. This speed grade suits address decoding, bus interface logic, and medium-scale state machines where the 15 ns pin-to-pin delay keeps combinatorial paths within timing budget.
For new designs, consider a current-production 22V10 variant in the same package; for legacy BOM lines, this is a surplus/broker buy.
5V logic compatibility and 10-macrocell capacity
The 5V input voltage confirms direct compatibility with legacy 5V TTL and CMOS buses — no level translation needed on the input side. The 10 macrocells provide enough registered and combinatorial logic for typical glue-logic tasks: address decoders, chip-select generators, simple state machines, and bus-arbitration logic. The 15 ns speed defines the minimum clock period for registered paths and the combinatorial delay from input to output — a key figure for timing closure in a 5V system.
