Where 7400 fits

7400 connects to 2 worlds: technology, related numbers.

NAND is functionally complete — every other logic gate can be built from it — so this one package could in principle implement any digital circuit.

7400 is part of

Divisors (24): 1, 2, 4, 5, 8, 10, 20, 25, 37, 40, 50, 74, 100, 148, 185, 200, 296, 370, 740, 925, 1480, 1850, 3700, 7400

Other mathematical patterns

Documented appearance

The 7400 part number named an entire logic family, so one identifier came to label thousands of devices.

Connection

In TTL the AND gate is implemented as a NAND followed by an inverter, so the simpler function is the more complex part.

why?
Strength 0.50, confidence "high".

The 7400 contains four two-input NAND gates and gave its number to the entire 7400 TTL logic family. NAND is functionally complete, so any Boolean function can be realised using it alone.
