Current through base of transistor will be zero. In the circuit, When button is not pressed: The LED is connected to know the output status.

The chip has six gates which do NOT operation. Because base current is zero the transistor will be in OFF state. Under OFF sate the total supply voltage appears across the transistor. When you want TTL outputs. Choose the appropriate package depending on requirement. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Voltage appears at base of transistor and current flows through it. Now let us take a single gate of the six and connect it as shown in circuit diagram.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. The chip has six gates which do NOT operation.

7404 – 7404 Hex Inverter Datasheet

TL — Programmable Reference Xatasheet. Choose the appropriate package depending on requirement. The gates in this chip provide TTL logic outputs which are a must in some applications. The gates in this chip provide TTL logic outputs which are a must in some applications. When button is pressed: Under OFF sate the total supply voltage appears across the transistor. The chip is basically used where a logic inverter is needed.

Input here is 1A which is connected to button.

Because base current is present the transistor will turn ON. Output 1Y is connected to LED through a resistor. Here are few cases where 74LS04 is used. Inverter Gates in this chip provide output which is negated logic input. We have six of these gates in 74LS04 chip.

74LS04 Pinout, Features, Equivalent, Examples & Datasheet

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

74os04n we draw truth table based on above cases, we will have. Because base current is present the transistor will turn ON.

Voltage appears at base of transistor and current flows through it. TL — Programmable Reference Voltage. The internal connection of gates can be given as below. We can use one or all six of these gates depending on requirement.

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