3 Input Nand Gate Circuit Diagram. Figure below shows the schematic stick diagram and layout of three input nand gate the corresponding stick diagram of nor3 gate is shown below. This is an inverted and or nand function so this circuit does indeed behave as a 3 input nand gate.
As with the and function seen previously the nand function can also have any number of individual inputs and commercial available nand gate ic s are available in standard 2 3 or 4 input types. The arrows represent the euler paths. In the earlier section on nand gates this type of gate was created by taking an and gate and increasing its complexity by adding an inverter not gate to the output.
As in the case of two input and gate the same analysis can be done for the 3 input or more and gates.
However when we examine this circuit we see that the nand function is actually the simplest most natural mode of operation for this ttl design. Layout of logic gates. 3 nand gates for or gate circuit for x y z. Three input nand gate.
