4011 IC Quad 2-Input NAND Gate CMOS
The CD4011BE delivers four independent 2-input NAND gates inside a single IC, giving designers a flexible building block for a wide range of logic circuits. Engineers and hobbyists use it to build custom logic systems, including control circuits, timing applications, and combinational logic designs.
This IC uses CMOS technology, which reduces power consumption and increases noise immunity. You can operate it over a broad voltage range from 3V to 15V, allowing integration into both low-voltage and high-voltage digital systems. With its standard DIP-14 package, you can easily insert it into breadboards or solder it into prototype PCBs.
