The AND gate is a basic a digital electronic logic gate which gives an output HIGH (1) as a result, if both the inputs are High (1), and if neither or only one input is HIGH to the AND gate then output will be LOW (0). You learn about AND and OR gates and figure that’s not very hard. I have created a truth table and i have extracted the boolean expression using a karnaugh map. A NAND gate (sometimes referred to by its extended name, Negated AND gate) is a digital logic gate with two or more inputs and one output with behavior that is the opposite of an AND gate. If ground is the gate's common, then the grounded input is not at a logic false condition, but simply not part of the simulation. A PIC, costing just a couple of dollars, would replace all those chips, and probably give enhanced performance and functionality as well. If both of the digital inputs to the gate are the same, then output will be HIGH (1).
