The timing diagram for a two-input NAND gate is shown below. The gate is working correctly.
A NAND gate consists of an AND gate and an OR gate connected in series with each other.
The NAND gate is an example of combinational logic.
The symbol shown below is an AND gate.
In Boolean algebra, 1 · 0 = 0.
