The NAND Gate can be combined in ways to make all the other logic gates. This circuit demonstrates how to do just that!
The Circuit:
From Left to Right...
[AND, OR, NOT, NOR, XOR, XNOR]
Each 5V Source is an input that is tied to one of the SPDT switches to select HIGH/LOW for that given input.
The Info:
There are many reasons why companies use a particular type of gate in their designs and manufacturing processes. The first is obviously cost. The second is simplification. All CMOS and TTL integrated circuits ranging from the very easy to the ridiculously complex such as CPLDs and FPGAs generally use the same type of gate. More often than not this gate is the NAND gate. Although the NOR Gate can accomplish the same exact thing as well.
The circuit is inspired by the fact that when doing a search for NAND gates and how to construct their derivatives, not much was to be found. This circuit aims to fill in that gap and satisfy that niche for the community.
If this circuit has in some way helped you, please be sure to bookmark it! Also if you have any questions, comments, concerns or critiques please be sure to leave a comment.
****NOTE****
I have also done this same circuit showcasing the NOR Gate as well. Same exact principal and methods, just different gate is all. So be sure to check that one out too!
