Upper half is a line diagram showing four NAND gate symbols in a rectangle. Lower half is a photo of a grey rectangular integrated circuit package with metal pins on the two long sides, and lettering on top as described in the caption
The SN7400N chip contains four two-input NAND gates. The SN prefix indicates it was manufactured by Texas Instruments[1] The N suffix is a vendor-specific code indicating plastic DIP packaging. The second line of numbers (7645) is a date code; this chip was manufactured in the 45th week of 1976.[2]

The 7400 series is a popular logic family of transistor–transistor logic (TTL) integrated circuits (ICs).[3]

In 1964, Texas Instruments introduced the SN5400 series of logic chips, in a ceramic semiconductor package. A low-cost plastic package SN7400 series was introduced in 1966 which quickly gained over 50% of the logic chip market, and eventually becoming de facto standardized electronic components.[4][5] Since the introduction of the original bipolar-transistor TTL parts, pin-compatible parts were introcducted with such features as low power CMOS technology and lower supply voltages. Surface mount packages exist for several popular logic family functions.[6]
