LOGIC DIAGRAM OF EX NOR GATE
Explain The Logic EX-NOR Gate (Exclusive-NOR Gate) and Its
Fig 5 shows the pinout diagram of an IC 74266, a TTL quad-2 input EX-NOR gate. Fig 5. It contains four 2-input EX-NOR gates in a 14-pin DIP. Pulsed Operation of EX-NOR Gate. The pulsed operation of an EX-NOR gate is illustrated in fig 6 . Fig 6. Initially when one of the two inputs of the EX-NOR gate is low, the output is at low level.
Logic Gates using PLC Programming [Explained with Ladder
NOR Gate; EX-OR Gate; EX-NOR Gate; Note: The circuit diagrams are connected to make and break input (I) and output (Q) contact in series and parallel circuits. For all the circuit diagram, we are representing inputs (I1) and (I2) as switches, output (Q1) as coil/lamp. Let’s see the explanation for each logic gate with PLC implementation, 1
Exclusive-NOR (XNOR) Digital Logic Gate - Electrical
XNOR gate also known as Exclusive-NOR or Exclusive-Negative OR gate is “A logic gate which produces High state “1” only when there is an even number of High state “1” inputs”. For 2-input gate, it can be interpreted as when both of the inputs are same, then the output is High state and when the inputs are different , then the output is Low state “ 0 ”.
Logic NOR Gate Tutorial with Logic NOR Gate Truth Table
The logic or Boolean expression given for a logic NOR gate is that for Logical Multiplication which it performs on the complements of the inputs. The Boolean expression for a logic NOR gate is denoted by a plus sign, ( + ) with a line or Overline, ( ‾‾ ) over the expression to signify the NOT or logical negation of the NOR gate giving us the Boolean expression of: A+B = Q.
Exclusive-NOR Gate with Ex-NOR Gate Truth Table
Giving the Boolean expression of: Q = AB + AB The logic function implemented by a 2-input Ex-NOR gate is given as “ when both A AND B are the SAME ” will give an output at Q general, an Exclusive-NOR gate will give an output value of logic “1” ONLY when there are an EVEN number of 1’s on the inputs to the gate (the inverse of the Ex-OR gate) except when all its inputs are

Logic diagram Truth Table NOR Gate. A NOT-OR operation is known as NOR operation. It has n input (n >= 2) and one output. Logic diagram Truth Table XOR Gate. XOR or Ex-OR gate is a special type of gate. It can be used in the half adder, full adder and subtractor. The exclusive-OR gate is abbreviated as EX-OR gate or sometime as X-OR gate.
Logic Gates | Electronics Club
Gates are identified by their function: NOT, AND, NAND, OR, NOR, EX-OR and EX-NOR. Capital letters are normally used to make it clear that the term refers to a logic gate. Note that logic gates are not always required because simple logic functions can be performed with switches or diodes, for example: Switches in series (AND function)
