## Maximum Forward Current

Definition: The Maximum value of the forward current that a PN junction or diode can carry without damaging the device is called its Maximum Forward Current. The rating of a PN junction or a diode is specified by the manufacturer in its datasheet. However, if the forward current in a diode is increased beyond this specified …

## Maximum Power Rating

Definition: The Maximum Power Rating is defined as the maximum power that a PN junction or diode can dissipate without damaging the device itself. Usually, it is specified by the manufacturer in, its datasheet. The power dissipated at the junction is equal to the product of junction current and the voltage across the junction. If …

## Boolean Theorems

Boolean theorems and laws are used to simplify the various logical expressions. In a digital designing problem, a unique logical expression is evolved from the truth table. If this logical expression is simplified the designing becomes easier. The boolean algebra is mainly used in digital electronics, set theory and digital electronics. It is also used …

## JK Flip Flop

The JK Flip Flop is the most widely used flip flop. It is considered to be a universal flip-flop circuit. The sequential operation of the JK Flip Flop is the same as for the RS flip-flop with the same SET and RESET input. The difference is that the JK Flip Flop does not the invalid …

## Exclusive NOR Gate – EXNOR Gate

EXNOR gate means exclusive NOR gate and is a combination of X-OR and NOT gate. It also has two inputs and one output. When both the inputs are at 0, the output of the  EXNOR gate will be high i.e.1. If one of the input is 0 and the other is 1 the output will …

## Exclusive OR Gate – EXOR Gate

The EXOR gate is used extensively in digital data processing circuits and is known as Exclusive-OR-gate. The EXOR gate has a high output only when an odd number of inputs are high. For the two input EXOR gates, the output will be high when the set of input is either 01 or 10. The XOR …

## NAND Gate

The NAND gate is a combination of an AND gate and NOT gate. They are connected in cascade form. It is also called Negated And gate. The NAND gate provides the false or low output only when their outputs is high or true. The NAND gate is essential because different types of a boolean function …

## NOR Gate

An OR gate followed by a NOT gate in a cascade is called a NOR gate. In other words, the gate which provides a high output signal only when there are low signals on the inputs such type of gate is known as NOR gate. The logic symbol of the gate is shown below: The …

## NOT Gate

The NOT gate is a single input single output gate. This gate is also known as Inverter because it performs the inversion of the applied binary signal, i.e., it converts 0 into 1 or 1 into 0. In other words, the gate which has a high input signal only when their input signal is low …

## AND Gate

AND gate also has two or more input signals same as that of the OR gate, and the output is single. The gate has a high output only when all the input signals are high otherwise the output signal is low. The logic symbol for the gate is shown below. The switching circuit of the …
