The LED is connected to know the output status. Because base current is zero the transistor will be in OFF state.

TL — Programmable Reference Voltage. We have six of these gates in 74LS04 chip. Because base current is present the transistor will turn ON. We have six of these gates in 74LS04 chip. These NOT gates perform Inverting function.

In the circuit, When button is not pressed: Voltage appears at base of transistor and current flows through it. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Choose the appropriate package depending on requirement. We can use one or all six of these gates depending on requirement. Now dataaheet us take a single gate of the six dtasheet connect it as shown in circuit diagram.

These NOT gates perform Inverting function. Voltage appears at base of transistor and current flows through it. Inverter Gates in this chip provide output which is negated logic input. Under OFF sate the total supply voltage appears across the transistor.

Submitted by admin on 4 April As shown in diagram, we have a transistor forming a NOT gate. The description for each pin is given below. The gates in this chip provide Datashee logic outputs which are a must in some applications. Inverter Gates in this chip provide output which is negated logic input.

The internal connection of gates can be given as below. If we draw truth table based on above cases, we will have.

Under OFF sate the total supply voltage appears across the transistor. Under such case the output 1Y here will be HIGH, since output is nothing but voltage dattasheet transistor. If we draw truth table based on above cases, we will have. Submitted by admin on 4 April The internal connection of gates datashheet be given as below. Here are few cases where 74LS04 is used. The chip is basically used where a logic inverter is needed.

National Semiconductor

TL — Programmable Reference Voltage. In the circuit, When button is not pressed: When button is pressed: Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. When you want TTL outputs. The chip has six gates which do NOT operation. Output 1Y is connected to LED through a resistor. The series are digital logic integrated circuits. The series are digital logic integrated circuits.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Input here is 1A which is connected to button. We can use one or all six of these gates depending on requirement.
