CD4077 belongs to the CD4000 IC series and is a Quad 2-input exclusive NOR gate designed using complementary MOS (CMOS) technology integrated with P & N type enhancement mode transistors. This IC enables design engineers to implement positive logic exclusive NOR gates directly. It offers a wide range of working voltages and conditions, high noise immunity, and static protection through clamping diodes.
What is an EXCLUSIVE-NOR Gate?
An XNOR Gate is a type of digital logic gate that receives two inputs and produces one output. All inputs are treated with the same logic, responding equally to similar inputs. It is also known as an ‘Equivalence Gate’. If all inputs to the XNOR gate are 0, the gate will produce a 1. If all inputs are 1, the gate will also produce a 1. However, if any input to the gate differs from the other, the gate will output a 0.
Applications:
- Logical Comparators
- Adders/Subtractors
- Parity Generators and Checkers
