7.5 ns propagation delay — the timing ceiling
The ATF22V10C-7PC is a 22V10-architecture EE PLD from Microchip, rated at 7.5 ns pin-to-pin propagation delay. That 7.5 ns sets the maximum system clock frequency the part can sustain without wait-state insertion — roughly 133 MHz combinatorial, though registered flip-flop performance will be lower. The 10 macrocells give you ten sum-of-product logic terms, enough to absorb address decoding, bus arbitration, or state-machine sequencing that would otherwise eat a handful of 74-series logic packages.
5V supply, through-hole footprint
Runs on a single 5V rail — no core I/O split, no LDO needed if your board already has 5V. That means hand-assembly is straightforward, but it also means this part does not fit an SMT reflow profile. The 24-PDIP supplier package code confirms the standard 0.100-inch pin pitch layout.
Microchip lists the ATF22V10C-7PC as obsolete.
