The LED is connected to know the output status. Because base current is present the transistor will turn ON. These NOT gates perform Inverting function.

The chip has six gates datxsheet do NOT operation. The LED is connected to know the output status. We have six of these gates in 74LS04 chip. Current through base of transistor will be zero. Now let us take a single gate of the six and connect it as shown in circuit diagram.

74LS04 Datasheet

The gates in this chip provide TTL logic outputs which are a must in some applications. Output 1Y is connected to LED through a resistor.

Submitted by admin on 4 April If we draw truth table based on above cases, we will have. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Choose the appropriate package depending on requirement.

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. We have six of these gates in 74LS04 chip.

National Semiconductor

As shown in diagram, we have a transistor forming a NOT gate. We can use one or all six of these gates depending on requirement.

The chip has six gates which do NOT operation.

The internal connection of gates can be given as below. TL — Programmable Reference Voltage. Choose the appropriate package depending on requirement.

Because base current is zero the transistor will be in OFF state. Inverter Gates in this chip provide output which is negated logic input. Submitted by admin on 4 April The chip is basically used where a logic inverter is needed. Here are few cases where 74LS04 is used. The chip is basically used where a logic 74lx04n is needed. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

74LS04 Pinout, Features, Equivalent, Examples & Datasheet

Output 1Y is connected to LED through a resistor. The gates in this chip provide TTL logic outputs which are 74lss04n must in some applications. Input here is 1A which is connected to button. When you want TTL outputs.

The description for each pin is given below. 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. If we draw truth table based on above cases, we will have. Inverter Gates in this chip provide output which is negated logic input.
