SN7400N - The company prefix SN indicates this is a Texas Instruments manufactured part. This can also be confirmed through the TI logo.

Manufacturer Prefix or IC Company Prefix or ID are identification codes various semiconductor companies use to identify their integrated circuits. Those IDs are usually found as the first few letters of the part number. They may often be found on the IC package itself as well along with a possible logo.
