Sega JVS I/O - identifying/replacing a dead 14-pin IC

[aoiddr]

I was hooking up one of my Sega JVS I/O Type 1 (837-13551-92) boards to a new power supply and made the mistake of trusting a wiring harness...and ended up swapping the 12V and 5v lines and that cooked IC8S on the bottom of the board.

Anyone happen to know of a replacement chip I can swap this bad chip with to see if it can resurrect this I/O board? It's a 14-pin surface mount chip with "P11AB" written on it. Thanks.

maybe 74hc04

desolder it, it looks like the part numbers may be printed on the board under them.

Original is a Fairchild 74VHC04.
