The ATF22V10C-10SU is a 5V EE PLD from Microchip's 22V10 series with a 10 ns propagation delay. That 10 ns pin-to-pin speed provides timing margin for address decoding and glue logic.
5V-only rail — what it means for mixed-voltage boards
This part runs on a single 5V supply. If your board also carries 3.3V or 1.8V logic, you will need level translation on the I/O lines — the ATF22V10C-10SU does not tolerate 3.3V inputs as valid logic-high.
Microchip lists the ATF22V10C-10SU as Active.
