CD4072 is a part of the CD4000 IC series. CD4072 is a Triple 3-Input OR Gate that allows designers of the positive-logic OR function and supplements the existing family of CMOS gates. The IC is usually available in a 14-pin hermetically sealed dual in line (DIP) packages. The IC offers many features such as high noise immunity and ESD barring. CD4072 is small in size and is directly interfaceable with TTL, CMOS, NMOS and other devices.
What is OR Gate?
The OR gate is a digital logic gate that is generally used in digital logic design. The output of an OR gate is high or 1, if even a single input to the gate is at a logical high. on the other hand, An OR gate will yield a logical Low if anyone of its input go LOW.
