Submitted by admin on 5 April We can use one or all gates.

Using continuously under heavy loadsns Per input: With them the switching delays of gates are minimized. Previous 1 2 The chipis basically used when NOR logic function is required. In that state the current flow through base of both transistors will be zero.

Here are a few cases why it is used. Because transistor drop is zero Y1 will be LOW. This output is connected to a LED trough a current limiting resistor. When one of buttons is pressed. With that the total drop across both transistors will be zero. These two inputs are connected datasjeet buttons.

No abstract text available Text: This LED is connected to detect the state of output. Exceeding any of the absolute maximum ratings, even datasheey, lead to deterioration in ICcurrent Per input: After verifying the three states, you can tell that we have satisfied the above truth table.


Output of the gate is taken out from joint collector of both transistors.

Now let us consider a few states: The buttons are connected to change the logic datasheeet inputs. Because of this the chip can be used high speed applications. TL — Programmable Reference Voltage. Both transistors will be ON and voltage across both of them will be zero. The internal circuit is composed of 3 stages, including.

74LS02 NOR Gate IC Pinout, Features, Equivalents, Circuit & Datasheet

The internal circuit is composed of 3 stages, including aCompatible with TTL outputs. Using continuously under heavy loads.

The description for each pin is given below. Where high speed NOR operation is necessary. Has buffered outputs, improving the output transition characteristics. LI dataasheet, IF netlist writer version 4.

They are also plug in replace ments for LSTTL devices giving avalue of datazheet IC ‘s internal equivalent capacitance which is calculated from the operating current. It is really popular and is available everywhere. 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.

VCC-Connected to positive voltage to provide power to all four gates. The chip has four NOR gates in it. The four NOR gates in the chip mentioned earlier are connected internally as shown below. For realizing the datashedt truth table let us take simplified NOR gate and have it connected as shown below.


Lc this we can use each gate of the chip depending on requirement. 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.

Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even. The chip is available in different packages and is chosen depending on requirement. When you want logic inverter. In the circuit two transistors are connected to form a NOR gate.

When both buttons are pressed. When both buttons are not pressed. The two inputs are driven out from bases of two transistors. The chip also provides TTL outputs which are a must in some systems.
