Voltage appears at base of transistor and current flows through it. The description for each pin is given below. The gates in this chip provide TTL logic outputs which are a must in some applications.

These Daatsheet gates perform Inverting function.

National Semiconductor

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. TL — Programmable Reference Voltage. As shown in diagram, we have a transistor forming a NOT gate.

Because base current is zero the transistor will be in OFF state. The description for each pin is given below. If we draw truth table based on above catasheet, we will have. Under OFF sate the total supply voltage appears across the transistor.

The internal connection of gates can be given as below. Submitted by admin on 4 April When you want TTL outputs. When button is pressed: If we draw truth table based on above cases, we datxsheet have. Here are few cases where 74LS04 is used. We can use one or all six of these gates depending on requirement. Under OFF sate the total supply voltage appears across the transistor.

Input here is 1A which is connected to button.

Under ON sate the total supply voltage appears datashet the resistor and voltage across transistor will be zero. In the circuit, When button is not pressed: Here are few cases where 74LS04 is used. Output 1Y is connected to LED through a resistor. We can use one or all six of these gates depending on requirement.

The chip has six gates which do NOT operation. When button is pressed: The internal connection of gates can be given as below. Input here is 1A which is connected to button. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

Inverter Gates in this chip provide output which is negated logic input. TL — Dayasheet Reference Voltage. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

Now let us take a single gate of the six and connect it as shown in circuit diagram. The LED is connected to know the output status. Because base current is present the transistor will turn ON.

Now let us take a single gate of the six and connect it as shown in circuit diagram. Choose the appropriate package depending on requirement. 74ls0n4 series are digital logic integrated circuits. Because base current is present the transistor will turn Datashet. The chip is basically used where a logic inverter is needed.

The LED is connected to know the output status. The chip has six gates which do NOT operation. Output 1Y is connected to LED through a resistor. We have six of these gates in 74LS04 chip.

Inverter Gates in this chip provide output which is negated logic input.

Current through base of transistor will be zero. Submitted by admin on 4 April
