The 7400 series contains TTL (Transistor-Transistor-Logic) circuits which were build already in the 60s. The ICs were widespread and can be found until today.
Compare to the 4000 series the 7400 are faster, but consume more power and are designed for 5 V only.

The prefix letters indicate the manufacturer. Important for the function is just the number. Letters between the number means special additional characteristics like slow, fast or low power.

Example:
The 7400 you can find as
SN7400
SN74LS00
