I think it's the old markings for a MCP614x op-amp. I "had" labeled the drawer as an op-amp.

I know it's 8-lead, pretty sure it's msop, but it can be any of MCP6141, MCP6142 or MCP6143.

I checked my order history at Digikey, Mouser, Newark, MicrochipDirect, even eBay, Amazon and AliExpress. No clue where I got these. I'm guessing a "lot purchase" on ebay a long time ago.
