We can use one or all gates. For realizing the above truth table let us take simplified NOR gate and have it connected as shown below.

When you want logic inverter. The internal circuit is composed of 3 stages, including.

Using continuously under heavy loads. Previous 1 2 When both buttons are not pressed. The four NOR gates in the chip mentioned earlier are connected internally as shown below. Submitted by admin on 5 April Because of this the chip can be used high speed applications. Both transistors will be ON and voltage across both of them will be zero.

74LS02 Datasheet

The chip has four NOR gates in it. These two inputs are connected to buttons.


VCC-Connected to positive voltage to provide power to all four gates. After verifying the three states, you can tell that we have satisfied the above truth table.

They are also plug in replace ments for LSTTL devices giving a reductionC pd n pd isdelined as the value otthe IC ‘s internal equivalent capacitance which is calculated.

LIIF netlist writer version 4. TL — Programmable Reference Voltage. The chip also provides TTL outputs which are a must in some systems. In the circuit two transistors are connected to form a NOR gate. The buttons are connected to change the logic of inputs.

Where high speed NOR operation is necessary. The description for each pin is given below.

7402 – 7402 Quad 2-Input NOR Gate Datasheet

Output of the gate is taken out from joint collector of both transistors. Exceeding any of the absolute maximum ratings, even 74ls002, lead to deterioration in IC performance or even.

Using continuously under heavy loadsns Per input: With that the total drop across both transistors will be zero. In that state the current flow through base of both transistors will be zero. And if your project doesn’t require a specific brand of ICselect from thedoesn’t require a specific brand of ICselect from the functionally equivalent Jameco Value Offering.


Because transistor drop is zero Y1 will be LOW. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in ICcurrent Per input: The chip is available in different packages and is chosen depending on requirement.

With them the switching delays of gates are minimized. They are also plug in replace ments for LSTTL devices giving avalue of the IC ‘s internal equivalent capacitance which is calculated from the operating current. Like this we can use each gate of the chip depending on requirement. Here are a few cases why it is used.

It is really popular and is available everywhere. Has buffered outputs, improving the output transition characteristics.
