How do you make a NOR gate XOR gate?

How do you make a NOR gate XOR gate?

Exclusive OR Gate, also known as EX OR Gate or XOR Gate, is an important digital logic gate, which implements an exclusive or logic i.e., the output is HIGH if and only if one of the inputs is HIGH. If both the inputs are LOW or HIGH, then the output is LOW….XOR Truth Table.

How many pins does a XOR gate have?

XOR gates are logic gates with the combination of two NOT, two AND & one OR gate. The output state gets LOW only at the same inputs….74LS85 Pinout Diagram.

How do I check my 741 IC?

Testing a 741 IC A voltage is applied to pin3 of the op-amp through the variable resistor (10K). All we need to do is to verify whether the voltages V1 and V2 are exactly same or not. Check them using a multi-meter.

How can we make ex OR gate using NAND gate?

XOR. An XOR gate is made by connecting four NAND gates as shown below. This construction entails a propagation delay three times that of a single NAND gate. , noting from de Morgan’s Law that a NAND gate is an inverted-input OR gate.

What is the use of pin number 8 in IC 741?

Not Connected Pin: Pin 8 It is just a pin that is used to fill up the empty pin in the IC 741 Op Amp. It has no connection with any of the internal or external circuits.

How does a 741 op amp power supply work?

This is a voltage regulator using the Zener diode and OP AMP. The circuit is used for controls the voltage battery is very steady. This circuit applies a very low current to about 1mA only. Thus there is a ripple voltage of about 1 mV at input voltage changing between 10 to 30 volts.

Why does the IC 741 require dual power supply?

It needs to avoid use of capacitors and voltage divider bias mainly. For that differential input and output and dual supply implemented. In differential amps we use constant current source, ie current mirror. So for the biasing, it needs dual supply.

What is the output of an ex-NOR gate for an even number?

The output of an Exclusive-NOR gate only goes to logic high when its two input terminals say A and B are at the same logic level which can be either at a logic one or a logic zero. In other words, one can understand this way that the output of an Ex-NOR gate for an even number 1’s on is logic high at the output, otherwise is at logic low.

What are Ex-nor and ex-or gates in IC?

These EX-OR gates are followed by NOT gates. These gates provides inverted output of EX-OR gate, so with both, we will have EX-NOR gate. Here we use 74LS04 HEX NOT gate chip. Pin diagram of 74LS04 IC is shown below.

What is the logic symbol of an ex-NOR gate?

The logic symbol of an Ex-NOR gate is an Ex-OR gate with the inversion bubble or the circle in the figure to describe the NOT function. Therefore, the Exclusive-NOR gate is also called the complementary form of the Exclusive-OR or Ex-OR gate. The Ex-NOR gate boolean expression is given by:

What is the voltage between pin 4 and pin 7?

Pin 4 and pin 7 are the negative and positive voltage power supply terminals. The power which is required for the IC to function is received from both these pins. The voltage level between these pins can be in the range of 5 – 18V.
