Three different variants of Chinese fake ULN2803 chips available on Amazon and eBay. No genuine chips are available on either.
Bonus: “18 pin” DIP socket from Chinese mega-dumpshit-flooder uxcell, who deserve their very own angry shitpost. Hey at least they didn’t send me mis-molded automotive trim clips instead of LED mounting bezels OH WAIT THEY DID
I’ve used up all my actually genuine ULN2803s so I don’t have one for comparison, sorry. 🙁
