A quad 2-input NAND gate is hardly the most exciting or exotic of components unless you have a pressing need for a bit of logic glue, so having secured a few we could hook up an LED or make an ...

This CMOS two-input combination NAND/NOR gate is a three-input, fourpin logic gate. A p-channel enhancementtype MOSFET (Q1) and an n-channel enhancement-type MOSFET (Q4) form ...
