Refer the pin diagram of the nand gate.....

The 7400, designates a device containing four two-input NAND gates. Each gate uses two pins for input and one pin for its output, and the remaining two contacts supply power (+5 V) and connect the ground. The 4000 series, the newer CMOS versions of the 7400 series are also usable as analog amplifiers using negative feedback (similar to operational amplifiers with only an inverting input).

7400ics pin has total 14 pin. Pin no 7 use for GND and pin no 14 used for +vcc, remaining pin used for connections. For a NAND gate two input is required and one output is obtained means for NAND gate 3 pin connection is required.

SO IN 7400ICS TOTAL 4 NAND GATE ARE CONNECTED.
