Where to use SN54LS00 IC?

SN54LS00 is a 2-input 4 NAND gate IC and used in many electronic circuits. SN54LS00 used for performing NAND function. When you want to use it as a logic inverter, NAND gates in this chip can be reconfigured to make them NOT gate.  So we can make SN54LS00 a four NOT gate chip if necessary. It can be used where high-speed NAND operation is necessary. This chip has lower transition times which are needed for high-speed applications, so SN54LS00 can be used in high-frequency systems.

How to Use SN54LS00 IC

As mentioned earlier, SN54LS00 has four NAND gates. The internal connection of four gates is shown below.

SN54LS00 Internal Circuit
SN54LS00 has 12 input-output pins for four NAND gates. To use the SN54LS00 IC, just power it using the Vcc and ground pins. The typical operating voltage of the IC is +5V, but it can also be operated in +7V. The output voltage of the IC on the pin Y will be equal to the operating voltage of the IC. As per the NAND gate truth table, when both the input of the Gate is Low the output will be high, otherwise, it will be low.
