I just intuit which bit is the part number, then Google it. If the same number has meanings outside electronics, adding "ic", "pinout", "datasheet" etc. might help.

It's better to work with fragments of the number, not the whole thing. For example, "16390" finds the Texas Instruments SN74CBT16390 mux/demux, which may or may not be similar to what you're seeing.

If Google lets you down, try feeding the number to Mouser, Digikey, Octopart, RS, Farnell, ...

4054 is likely to be this
For small parts like transistors, somewhere on the internet, there is a list of the most often used codes for transistors...

There is also the ecadata database

Where a search for A7 brings up this result.
