Cheap MAX485 chips

Anyone had any luck getting these cheap MAX485 chips to work? https://www.ebay.com.au/itm/10pcs-MAXIM-MAX485CPA-MAX485-DIP-8-RS-485-RS-422-Transceiver-new/232448697668?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D1%26asc%3D52547%26meid%3Da3b02c27d1f84afd950102b6d48f0f9e%26pid%3D100010%26rk%3D2%26rkt%3D12%26sd%3D232448697608%26itm%3D232448697668&_trksid=p2047675.c100010.m2109

I have a feeling they are not real MAX485 chips and possibly don't even work but the price is very tempting.

I don't know about your supplier but I have bought MAX485 chips from another ebay seller for about the same price point and so far they work fine. I would maybe not use them in a commercial product but they have been fine for my projects.

I also bought lots if max485 chips from other ebay sellers and work fine. I even bought some max3085 from ebay that also work ok.

Ok cheers, I'll try my luck.
