Inverter Gates in this chip provide output which is negated logic input. We have six of these gates in 74LS04 chip. Choose the appropriate package depending on requirement. When button is pressed: Because base current is present the transistor will turn ON. The description for each pin is given below.

In the circuit, When button is not pressed: Under such case dtasheet output 1Y here will also be LOW, since output is nothing but voltage across transistor. Input here is 1A which is connected to button. These NOT gates perform Inverting function.

Here are few cases where 74LS04 is used. In the circuit, When button is not pressed: As shown in diagram, we have a transistor forming a NOT gate. The chip is basically used where a logic inverter is needed. The series are digital logic integrated circuits. Because base current is zero the transistor will be in OFF state. Now let us take a single gate of the six and connect it as shown in circuit diagram.

If we draw truth table based on above cases, we will have. When button is pressed: TL — Programmable Reference Voltage. Under OFF sate the total supply voltage appears across the transistor. The gates in this chip provide TTL logic outputs which are a must in some applications. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

The series are digital logic integrated circuits. The chip is basically used where a logic inverter is needed.

Under OFF sate the total supply voltage appears across the transistor. As shown in diagram, we have a transistor forming a NOT gate. Under ON sate the total supply voltage appears across the resistor and voltage across transistor datasheeet be zero.

We can use one or all six of these gates depending on requirement. Voltage appears at base of transistor and vatasheet flows through it. Inverter Gates in this chip provide output which is negated logic input. Voltage appears at base of transistor and current flows through it. Input here is 1A which is connected to button.

Because base current is present the transistor will turn ON. The LED is connected to know the output status. The description for each pin is given below.

TL — Programmable Reference Voltage. Here are few cases where 74LS04 is used.

If we draw truth table based on above cases, we will have. Current through base of transistor will be zero. These NOT gates perform Inverting function.
