Logic Gate with Ladder Diagram
- Logic gates represented by a Boolean function.
- Electronic gates need a power supply to operate.
- Input supply required two voltage. eg. 0V and 5v which represent logic 0 and logic 1.
- Output of gate provide two nominal value of voltage.
Here we discuss OR, AND, NOT, NOR, NAND, EX-OR, EX-NOR logic gates with Truth Table and Boolean equation And also show Ladder logic according to gates.
1. OR gate
The OR gate is an electronic circuit that gives a high output 1 when one of the inputs is high.
The OR gate symbol, boolean equation, truth table and ladder logic as shown in the below figure.
2. AND gate The AND gate is an electronic circuit that gives a high output 1 when both inputs are high.
The AND gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
3. NOT gate
The NOT gate is an electronic circuit that gives invert version of input
The NOT gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
4. NOR gate The NOR gate is known as a universal gate which is made from two basic gates OR + NOT
The NOR gate is an electronic circuit that gives invert version of OR gate
It gives a high output 1 when both inputs are low.
The NOR gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
The NOR gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
5. NAND gate The NAND gate is known as a universal gate which is made from two basic gates AND + NOT
The NAND gate is an electronic circuit that gives invert version of AND gate
It gives a high output 1 one of the inputs is HIGH.
The NAND gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
6. EX-OR gate The EX-OR gate is an electronic circuit that gives a high output 1 when two inputs value is different from each other.
From the same input value, the output will be low
The EX-OR gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
The EX-OR gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
6. EX-NOR gate
The EX-NOR gate is an electronic circuit that gives a high output 1 when both inputs are same
The EX-NOR gate is an electronic circuit that gives a high output 1 when both inputs are same
The different input value from each other, the output will be low
The EX-OR gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
The EX-OR gate symbol, boolean equation, truth table, and ladder logic as shown in the below figure.
