Because base current is zero the transistor will be in OFF state. Because base current is present the transistor will turn ON. The internal connection of gates can be given as below. Input here is 1A which is connected to button.
We have six of these gates in 74LS04 chip. The internal connection of gates can be given as below.
The series are digital logic integrated circuits. Under such case the output 1Y here will be HIGH, since output is datashet but voltage across transistor.
7404 – 7404 Hex Inverter Datasheet
The chip is basically used where a logic inverter is xatasheet. Current through base of transistor will be zero. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.
When button is pressed: These NOT gates perform Inverting function. We can use one or all six of these gates depending on requirement.
The chip has six gates which do NOT operation. The gates in this chip provide TTL logic outputs which are a must in some applications. Choose the appropriate package depending on requirement. In the circuit, When 74ls04h is not pressed: When you want TTL outputs.
Submitted by admin on 4 April We have six of these gates in 74LS04 chip.
Input here is 1A 74l04n is connected to button. Inverter Gates in this chip provide output which is negated logic input. Now let us take a single gate of the six and connect it as shown in circuit diagram.

The chip is basically used where a logic inverter is needed. Because base current is zero the transistor will be in OFF state. The chip has six gates which do NOT operation. As shown in diagram, we have a transistor forming a NOT gate.
Output 1Y is connected to LED through a resistor. The description for each pin is given below.
Voltage appears at base of transistor and current flows through it. The description for each pin is given below. Here are few cases where 74LS04 is used.
We can use one or all six of these gates depending on requirement. The series are digital logic integrated circuits. These NOT gates 74,s04n Inverting function.
