You got the DOD 680?
Yeah, that chip is unobtanium basically... a substitute would probably require a daughter-PCB with all kinds of wires to switch around the non-matching pin-outs.
I have 2, one is broken.
I spent some time looking into it last night, and agree. Known substitutes seem to be different enough you can't just drop it in and expect it to work or not fry itself. Depends how far down the rabbit hole @paulyc wants to go. When does this become Beyond Economic Repair?
I got the pedal for free when I bought two DOD flangers, so idk how much I want to spend on a chip, I’d say up to $150 because I’d guess that’s what the pedal might be worth. It’s a paperweight now…
Maybe see if you can get this guy to sell the working one for much cheaper? https://reverb.com/item/49162962-reticon-sad4096
I've also seen pinball replacement boards that originally had this chip on it, not sure if the replacements do or not. If you're handy with electronics I think you could spin up a daughter board with substitute for less than that price assuming your time isn't worth anything, but I haven't sat down and verified that.
I saw a few posts on the pinball replacement boards, but all were dead ends.
I had dealings with that seller on reverb… let’s just say I’m good.
Noted.

This chip was used in a number of synths as well as the MXR M-166, M-205 Stereo Chorus, M-206, and Omni. There is a replacement board for about $100. Alternatively you could check out old government/military uses and try oemsemi who claims to have 24k+ on hand or aeri who claim to have 9k+ on hand.

I know this place..
Used to go there, back in the day and buy CPUs and RAM at wholesale prices.

There's likely other options including sending the original datasheet to someone who does asics and having them fab some. Probably would be cheap, relatively. Texas Instruments, anyone?
