Here are a few cases why it is used.

7402 – 7402 Quad 2-Input NOR Gate Datasheet

Because transistor drop is zero Y1 will be LOW. In the circuit two transistors are connected to form a NOR gate. 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 both buttons are not pressed. The chip also provides TTL outputs which are a must in some systems. Using continuously under heavy loadsns Per input: Where high speed NOR operation is necessary. Submitted by admin on 5 April These two inputs are 74lss02 to buttons. The description for each pin is given below. The two inputs are driven out from bases of two transistors.

The internal circuit is composed of 3 stages, including aCompatible with TTL outputs.

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. Because of this the datasheey can be used high speed applications. This LED is connected to detect the state of output. Has buffered outputs, improving the output transition characteristics.

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 chipis basically used when NOR logic function is required. The chip has four NOR gates in it.

It is really popular and is available everywhere. VCC-Connected to positive voltage datahseet provide power to datasbeet four gates. With that the total drop across both transistors will be zero. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in ICcurrent Per input: The buttons are connected to change the logic of inputs.

LIIF netlist writer version 4. The four NOR gates in the chip mentioned earlier are connected internally as shown below.

When one of buttons is pressed. TL — Programmable Reference Voltage.

The chip is available in different packages and is chosen depending on requirement. Using continuously under heavy loads. Output of the gate is taken out from joint collector of both transistors.

In that state the current flow through base of both transistors will be zero.

The internal circuit is composed of 3 stages, including. We can use one or all gates.

Now let us consider a few states: Previous 1 2
