Nand Gate Transistor Diagram. The nand gate is actually somewhat special in that its also referred to as a universal logic gate being that it can be used in combinations to make. Normally open pushbuttons are used for the two inputs.
Transistor transistor logic nand gate the figure below shows a transistor transistor logic ttl nand gate. 4 input nand gate sticks layout i1 i2 i3 i4 out step 1. If any input is low 0 a high 1 output results.
Any other combination of inputs low high will cause the output to have a high logic level.
To build the nand gate just follow the schematic from the above image. Order gate wires on poly step 2. We can see that the output is a logic low when all inputs are in high logic level. The nand gate is actually somewhat special in that its also referred to as a universal logic gate being that it can be used in combinations to make.
