10 ns propagation delay — system timing margin
The ATF22V10C-10PU is a 5V EE PLD from Microchip's 22V10 family, offering 10 macrocells in a through-hole 24-DIP package. The 10 ns propagation delay sets the maximum clock frequency for registered logic and the input-to-output latency for combinatorial paths — a 10 ns part at 5V typically supports system clocks up to 100 MHz with adequate timing margin for address decoding, state machines, or bus interface glue.
Through-hole DIP — board integration and rework
The 24-pin DIP (0.300 inch row spacing) is a socket-friendly form factor for prototyping, legacy board repair, or low-volume production where wave-solder or hand-solder assembly is preferred. The through-hole mounting avoids the thermal and inspection complexity of surface-mount PLCC or TQFP packages, making it a straightforward drop-in for existing 22V10 socketed designs.
