Because of this the chip can be used high speed applications. When both buttons are pressed. For realizing the above truth table let us take simplified NOR gate and have it connected as shown below.

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.

When one of buttons is pressed.

Has buffered outputs, improving the output transition characteristics. The chipis basically used when NOR logic function is kc. The description for each pin is given below. Submitted by admin on 5 April LIIF netlist writer version 4. Using continuously under heavy loadsns Per input: It is really popular and is available everywhere.

7402 – 7402 Quad 2-Input NOR Gate Datasheet

Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even. Previous 1 2 The buttons are 74l02 to change the logic of inputs. Both transistors will be ON and voltage across both of them will be zero.

This output is connected to a LED trough a current limiting resistor. No abstract text available Text: The internal circuit is composed of 3 stages, including aCompatible with TTL outputs. In that state the datashedt flow through base of both transistors will be zero. These two inputs are connected to buttons. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in ICcurrent Per input: When you want logic inverter.

The chip has four NOR gates in it. Now let us consider a few states: Here are datasheeet few cases why it is used.

74LS02 Datasheet

The chip is available in different packages and is chosen depending on requirement. Using continuously 74,s02 heavy loads. After verifying the three states, you can tell that we have satisfied the above truth table. The internal circuit is composed of 3 stages, including. With that the total drop across both transistors will be zero. The two inputs are driven out from bases of two transistors. 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.

The chip also provides TTL outputs which are a must in some systems.

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. The four NOR gates in the chip mentioned earlier are connected internally as shown below. Because transistor drop is zero Y1 will be LOW. Where high speed NOR operation is necessary. When both buttons are not pressed.

Like this we can use each gate of the chip depending on requirement. In the circuit two transistors are connected to form a NOR gate. Output of the gate is taken out from joint collector of both transistors. Datsaheet can use one or all gates. TL — Programmable Reference Voltage. This LED is connected to detect the state of output.

VCC-Connected to positive voltage to provide power to all four gates. With them the switching delays of gates are minimized.
