Looking at few datasheets, I can't tell if these small EEPROM chips have internal ESD protection diodes to Vcc and to ground.
Do they have these ESD protections?

I don't think I have ever seen an 24c device with ESD protection.
But then again, I don't think I would ever connect a 24c device in a way that ESD would ever get to it.
ESD concerns implies you want the part connected to the outside world somewhere !!
Why would you do that ??!!

Almost always CMOS chips have such diodes. Failing that, some other kind of protection structure on the inputs, or they might never make it through the assembly process.
You can usually tell from the electrical characteristics.. absolute maximum ratings for inputs and outputs. If it's Vdd + X where X is around a diode drop, you have your answer.

How do you think your computer knows what monitor you're using? Several lines to a 24CxxxEEPROM are exposed at the HDE-15 connector.

I'll have to open my monitor and find out. ;-)

There are plenty of schematics online.
