74LS00 is a member of 74XXYY IC series. The 74xxyy ICs are logic gates of digital electronics. 74LS00 IC has four NAND gates. Also each gate has two inputs. Hence name QUAD TWO INPUT NAND GATE.
Where 74LS00 IC is Used?
There are many reasons of using 74LS00 in electronic circuits. Here are a few examples where it is used.
1. 74LS00 basically used for performing NAND function. The IC has four NAND gates in it. Each gate can be used separately.
2. When you want logic inverter. NAND gates in this chip can be reconfigured to make them NOT gate. So we can make 74ls00 a four NOT gate chip if necessary.
3. Where high speed NAND operation is necessary. This chip has less transition times which are needed for high speed applications. So 74LS00 can be used in high frequency systems.
4. 74LS00 is one of the cheapest IC. It is really popular and is available everywhere.
