I was browsing On-Semi just looking around when I ran across the NLS457.
I hit Google and Bing and after trying multiple search terms have came up with 0 hits would answer my question.
The weird part is that I can not find anything even mentioning it, wither at On-Semi or via search engines. I can't believe that they would go through efforts to design, make and sell a chip that has no purpose. It's a new chip(2018) in a small package and so might be useful in a modern device of some kind, I just don't have a clue what it could be.
It takes the output of two AND gates, each of which has an inverted input and feeds it to an OR gate. It looks like something that might clock related, but in that case I would have thought Schmidt trigger inputs would have helped it's usefulness.
It's most likely something real obvious, but all of my schooling was over 25 years ago, most of which was not working in electronics. I'm getting the feeling that I'm going to be feeling rather stupid after it is pointed out to me.

First of all, never feel stupid because you don't know what a component is used for. Most components are actually pretty fairly specific.
Looking through the speeds in that datasheet: it's unlikely this is modern technology. Feels like 1980's "low-voltage high speed logic", like 74LVCxxx.
And then ON Semi went on and produced 2 million and sold them for $10 a piece. Now, they're sitting on the remainder and decided to sell them as product.
