74HC00 basically used for performing NAND function. The IC has four NAND gates in it, each gate can be used separately. When you want logic inverter, NAND gates in this chip can be reconfigured to make them NOT gate. So we can make 74HC00 a four NOT gate chip if necessary.

Where high-speed NAND operation is necessary. This chip has fewer transition times which are needed for high-speed applications. So SN74HC00 can be used in high-frequency systems. 74HC00 is one of the cheapest IC. It is really popular and is available everywhere.

As mentioned earlier 74HC00 has four NAND gates. The internal connection of four gates is shown below.
