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

7404 – 7404 Hex Inverter Datasheet

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

The LED is connected to know the output status. Voltage appears at base of transistor and current flows through it.

These NOT gates perform Inverting function. The chip is basically used where a logic inverter is needed. We have six of these gates in 74LS04 chip. Inverter Gates in this chip provide output which is negated logic input.

The chip has six gates which do NOT operation.

If we draw truth table based on above cases, we will have. 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. Under OFF sate the total supply voltage appears across the transistor. As shown in diagram, we have a transistor forming a NOT gate.

Submitted by admin on 4 April Under OFF sate the total supply voltage appears across the transistor. Because base current is present the transistor will turn ON. Submitted by admin on 4 April Because base current is present the transistor will turn ON. Input here is 1A which is connected to button.

The series are digital logic integrated circuits.

Here are few cases where 74LS04 is used. When button is pressed: In the circuit, When button is not pressed: The description for each pin is given below.

Input here is 1A satasheet is connected to button. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. The gates in this chip provide TTL logic outputs which are a must in some applications.

74LS04 Pinout, Features, Equivalent, Examples & Datasheet

When you want TTL outputs. Under such case the datazheet 1Y here will be HIGH, since output is nothing but voltage across transistor. Output 1Y is connected to LED through a resistor. The LED is connected to know the output status.

Choose the appropriate package depending on requirement. Because base current is zero the transistor will be in OFF state. The description for each pin is given below.
