The LED is connected to know the output status. The series are digital logic integrated circuits. Submitted by admin on 4 April When button is pressed: Voltage appears at base of transistor and current flows through it. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

Output 1Y is connected to LED through a resistor. The description for each 74ls04 is given below. Choose the appropriate package depending on requirement.

The LED is connected to know the output status. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. 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. Output 1Y is connected to LED through a resistor.

As shown in diagram, we have a transistor forming a NOT gate. Because base current is zero the transistor will be in OFF state. Input here is 1A which is connected to button. Inverter Gates in this chip provide output which is negated logic input.

Here are few cases where 74LS04 is used. Because base current is present the transistor will turn ON. TL — Programmable Reference Voltage.

Because base current is dayasheet the transistor will turn ON. Current through base of transistor will be zero. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

If we draw truth table based on above dwtasheet, we will have. Submitted by admin on 4 April Here are few cases where 74LS04 is used. Now let us take a single gate of the six and connect it as shown in circuit diagram.

The gates in this chip provide TTL logic outputs which are a must in some applications. The series are digital logic integrated circuits. We have six of these gates datashheet 74LS04 chip. Because base current is zero the transistor will be in OFF state.

The chip has six gates which do NOT operation. Input here is 1A which dataasheet connected to button. When you want TTL outputs. Under OFF sate the total supply voltage appears across the transistor. In the circuit, When button is not pressed: Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

When you 74lw04n TTL outputs. These NOT gates perform Inverting function. When button is pressed: Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

The chip is basically used where a logic inverter is needed.

If we draw truth table based on above cases, we will have. Current through base of transistor will be zero. Now let us take a single gate of the six and connect it as shown in circuit diagram.

The description for each pin is given below. Inverter Gates in this chip provide output which is negated logic input. We have six of these gates in 74LS04 chip. The chip has six gates which do NOT operation. We can use one or all six of these gates depending on requirement. The chip is basically used where a logic inverter is needed. The internal connection of gates can be given as below. We can use one or all six of these gates depending on requirement.

TL — Programmable Reference Voltage. As shown in diagram, we have a transistor forming a NOT gate. Choose the appropriate package depending on requirement.
