In the circuit two transistors are connected to form a NOR gate.

LIIF netlist writer version 4. 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. TL — Programmable Reference Voltage. This output is connected to a LED trough a current limiting resistor.

It is really popular and is available everywhere. The four NOR gates in the chip mentioned earlier are connected internally as shown below.

With that the total drop across both transistors will be zero. The internal circuit is composed of 3 stages, including. The chipis basically used when NOR logic function is required. The description for each pin is given below. The chip is available in different packages and is chosen depending on requirement.

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

Because of this the chip can be xatasheet high speed applications. Like this we can use each gate of the chip depending on requirement. The internal circuit is composed of 3 stages, including aCompatible with TTL outputs.

No abstract text available Text: 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. Both transistors will be ON and voltage across both of them will be zero. We can use one or all gates.

This LED is connected to detect the state of output.

The chip also provides TTL outputs which are a must in some systems. Exceeding any of the absolute maximum ratings, even briefly, lead datsheet deterioration in ICcurrent Per input: Here are a few cases why it is used.

Submitted by admin on 5 April For realizing the above truth table let us take simplified NOR gate and have it connected as shown below. When both buttons are not pressed. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even. When one of buttons is pressed.

The two inputs are driven out from bases of two transistors. The buttons datashet connected to change the logic of inputs. Using continuously under heavy loadsns Per input: Output of the gate is taken out from joint collector of both transistors.

The chip has four NOR gates in it. When both buttons are pressed. Using continuously under heavy loads. Previous 1 2 These two inputs are connected to buttons. In that state the current flow through base of both transistors will be zero. VCC-Connected to positive voltage to provide power to all four gates.

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.

When you want logic inverter. Now let us consider a few states: After verifying the three states, you can tell that we have satisfied the above truth table. Because transistor drop is zero Y1 will be LOW.

Where high speed NOR operation is necessary. With them the switching delays of gates are minimized. Has buffered outputs, improving the output transition characteristics.
