I was reading an entry regarding an a six pin SMD marked 67A trying to find some details about it, and found a link to a MLX02367A which seems to be a common part but with no details.
Having fixed a lot of China based "stuff," I have found that most, if not all, started life at Texas Instruments who let old companies of the 80's and 90's like Philips make them under their own brand name.
These had some use of them, then of recent times farmed out to China to copy under other codes, most I found use part of the old code numbers but some get a new make over.
After searching through TI's data base, I found a UCC28742 which might fit (SOT23-6) which uses an opto-coupler format, their list also has others but they do not use an opto set up.
It would help if this can be confirmed, please.
