3 Input Nand Gate Schematic. There are several schematic designs used for nand gate. It can be done with just three gates.
The circuit isn t very good. Start from a truth table use k maps to minimize logic and draw the final circuit. Notice that the ab is a 2 input and gate which is equivalent to overline overline ab which is a 2 in nand gate followed by an inverter another 2 in nand with both inputs tied together.

Begingroup though to build that from nand nor gates would take four gates in total. Cd4011b cd4012b and cd4023b nand gates provide the system designer with direct implementation of the nand function and supplement the existing family of cmos gates. As in the case of two input and gate the same analysis can be done for the 3 input or more and gates.
