The CD4081 is a four-AND gate CMOS chip. An AND gate is a logic gate that only produces a HIGH output when all of its inputs are HIGH. This Integrated Circuit (IC) contains four AND gates, each with two inputs. As a result, it is frequently referred to as a Quad 2-Input AND Gate. The CD4081 is part of the CD4000 IC series. The CD4081 is a Quad 2-Input With Gate built with complementary MOS (CMOS) technology and N- and P-channel enhancement mode transistors. They have equal source and sink current capacities and adhere to the B series output drive standard. The integrated circuit has several characteristics, including thermal overload prevention and strong noise immunity. Clamping diodes safeguard each input of the IC from static harm. CD4081 is small in size and simple to operate, making it suitable for use with any device.

How AND gate Works?
An AND gate is one of the primary logic gates. It can have two or more inputs. It gives a HIGH output only when all of these inputs are HIGH. The basic AND gate have two inputs and you can see its symbol and truth table below.
