We have six of these gates in 74LS04 chip. 47ls04n the appropriate package depending on requirement. Because base current is zero the transistor will be in OFF state.

If we draw truth table based on above cases, we will have.

Input here is 1A which is connected to button. Submitted by admin on 4 April These NOT gates perform Inverting function. These NOT gates perform Inverting function. Because base current is zero the 74la04n will be in OFF state. The series are digital logic integrated circuits. If we draw truth table based on above cases, we will have.

Under such case the 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 present the transistor will turn ON.

Because base current is present the transistor will turn ON. Submitted by admin on 4 April 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 across transistor. Output 1Y is connected to LED through a resistor. TL — Programmable Reference Voltage.

When you want TTL outputs. Current through base of transistor will be zero. The series are digital logic integrated circuits. The gates in this chip provide TTL logic outputs which are a must in some applications. Input here is 1A which is datasheeh to button. The internal connection of gates can be given as below.

When button is pressed: When button is pressed: Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. The chip is basically used where a logic inverter is needed.

Now let us take a single gate of the six and connect it as shown in circuit diagram. Datasheett chip has six gates which do NOT operation. Inverter Gates in this chip provide output which is negated logic input.

The LED is connected to know the output status. When you want TTL outputs. In the circuit, When button is not pressed:
