If we draw truth table based on above cases, we will have. Under such case datashet output 1Y here will be HIGH, since output is nothing but voltage across transistor. The description for each pin is given below. Because base current is zero the transistor will be in OFF state.

The series are digital logic integrated circuits. The internal connection of gates can be given as below. As shown in diagram, we have a transistor forming a NOT gate. Because base current is zero the transistor will be in OFF state.

When you want TTL outputs.

When button is pressed: We have six of these gates in 74LS04 chip. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Here are few cases where 74LS04 is used. The chip is basically used where a logic inverter is needed. TL — Programmable Reference Voltage.

These NOT gates perform Inverting function. When button is pressed: We can use one or all six of these gates depending on requirement. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. The gates in this chip provide TTL logic outputs which are a must in some applications. Current through base of transistor will be zero. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. We have six of these gates in 74LS04 chip.

Current through base of transistor will be zero. The description for each pin is given below. These NOT gates perform Inverting function.

In the circuit, When button is not pressed: Input here is 1A which is connected to button. Choose the appropriate package depending on requirement. Submitted by admin on 4 April As shown in diagram, we have a transistor forming a NOT gate. Inverter Gates in this chip provide output which is negated logic input. 74s04n

Here are few cases where 74LS04 is used. Input here is 1A which is connected to button. Submitted by admin on 4 April Voltage appears at base of transistor and current flows through it. The LED is connected to know the output status. Output 1Y is connected to Datashee through a resistor. Now let us take a single gate of the six and connect it as shown in circuit diagram.

Choose the darasheet package depending on requirement.

Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Inverter Gates in this chip provide output which is negated logic input. When you want TTL outputs. If we draw truth table based 7ls04n above cases, we will have. The gates in this chip provide TTL logic outputs which are a must in some applications.

TL — Programmable Reference Voltage. Voltage appears at base of transistor and current flows through it. We can use one or all six of these gates depending on requirement.

Now let us take a single gate of the six and connect it as shown in circuit diagram. Because base current is present the transistor will turn ON. Output 1Y is connected to LED through a resistor. In the circuit, When button is 74ls40n pressed: Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

The chip is basically used where a logic inverter is needed. Because base current is present the transistor will turn ON. The chip has six gates which do NOT operation.

The series are digital logic integrated circuits.
