Again, this is just for fun so don't spend too much time on it.
It's a Texas Instruments part. I tried my previous methods without success.

Thanks!

 

Look for SN74AHC14N.

 

TI provides a package marking lookup tool:

You may have to play around with putting different parts of the marking on there as things like date codes can cause problems.
