CD4071 4071 Quad 2-Input OR Gate DIP-14

Product details of CD4071 4071 Quad 2-Input OR Gate DIP-14
The CD4070 is a CMOS chip with four XOR gates. Because each gate has two inputs and it has four gates inside, it’s usually called a Quad 2-Input XOR Gate.
This chip is more or less identical to the CD4030.
An XOR gate means exclusive OR, and will only give a HIGH output if one of the inputs is HIGH and the other is LOW. Or to say it in another way: The output from an XOR gate will be HIGH only if the inputs are not equal.
