The LED is connected to know the output status. Output 1Y is connected to LED through a resistor. Under such case the output 1Y datasheeh will also be LOW, since output is nothing but voltage across transistor. Submitted by admin on 4 April Under OFF sate the total supply voltage appears across the transistor. Datashest have six of these gates in 74LS04 chip. In the circuit, When button is not pressed: Current through base of transistor will be zero.

The series are digital logic integrated circuits. The internal connection of gates can be given as below. The description for each pin is given below. The LED is connected to know the output status.

74LS04 NOT Gate IC | IC Datasheet

The chip is basically used where a logic inverter is needed. Output 1Y is connected to LED through a resistor. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. When you want TTL outputs. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

As shown in diagram, we have a transistor 74ls004n a NOT gate. These NOT gates perform Inverting function. Now let us take a single gate of the six and connect it as shown in circuit diagram.

When button is pressed: The gates in this chip provide TTL logic outputs which are a must in some applications. When button is pressed: As shown in diagram, we have a transistor forming a NOT gate.

7404 – 7404 Hex Inverter Datasheet

Submitted by admin on 4 April dtasheet Now let us take a single gate of the six and connect it as shown in circuit diagram. Here are few cases where 74LS04 is used.

Here are few cases where 74LS04 is used. We have six of these gates in 74LS04 chip. If we datasbeet truth table based on above cases, we will have. The series are digital logic integrated circuits. Under OFF sate the total supply voltage appears across the transistor. Because base current is present the transistor will turn ON. Because base current is present the transistor will turn ON. In the circuit, When button is not pressed: Choose the appropriate package depending on requirement.

Under ON sate the total supply voltage appears datashheet the resistor and voltage across transistor will be zero. The chip is basically used where a logic inverter is needed. Under such case the output 1Y here will be 74lss04n, since output is nothing but voltage across transistor. The description for each pin is given below.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Because base current is zero the transistor will be in OFF state. These NOT gates perform Inverting function.

The internal connection dtaasheet gates can be given as below. Inverter Gates in this chip provide output which is negated logic input. Voltage appears at base of transistor and current flows through it.
