Description

74LS04 is a 2 input quadruple 8-bit NOT gate IC. Inverter basic functions are to invert the incoming logic whether it is HIGH or LOW. They are also known as NOT gates. Inverters are easy to design using NMOS and PMOS transistors. They have only one input and one output.

SPECIFICATIONS 

  • The supply voltage range for IC is 4.75V to 5.25. It can be increased up to 7V. More than 7V can make IC burn easily.
  • The maximum rise and fall time are faster for most of the controller the other TTL devices. It can rise and fall maximum in 15ns
  • The operating temperature of the IC is 0 to 70 degrees.
  • IC 74LS04 can draw an output current of 8mA on each gate. It’s the max range, more could harm the IC.

 

APPLICATIONS 74LS04

  • For general Logic conversion
  • 74LS04 used as an inverter in servers.
  • In the memory unit, the NOT gate is used widely.
  • PCs, Notebooks, and other smart computers come up with internal NOT gates.
  • In digital electronics or any digital system like networking also use gates to invert the states.

 

74LS04 Truth Table

The max voltages will lead the output state HIGH in the case of LOW input on the transistor. No matter how the inverter is designed. It will always give the output according to the following pattern. The input will always follow the following truth table on different inputs. All NOT gates following the following formula A = A’.
