# CD4001 IC It is 2-input NOR Gate IC. CD4001 IC is designed with 180nm CMOS technology in eSim consisting four NOR Gates. When both the inputs are LOW then only output is HIGH, otherwise LOW. It is also called inverted OR Gate, a type of Universal Gate. ## Usage/Examples The IC can be used for Noise Removing. Also used in devices such as PCs and notebooks. ## Documentation To know the details of CD4001 IC please go through with the documentation : [CD4001_datasheet](https://www.ti.com/lit/gpn/cd4001b) ## Comments/Notes Please note this is a complete digital IC. It works fine at the time of simulation. ## Contributer Name: Ankush Mondal Email: mondalankush369@gmail.com Year: 2022 Position: FOSSEE Summer Fellow 2022
