And Gate Diagram. An x or gate is a two input one output logic circuit. Here we are going to use ic 74ls09 for demonstration this chip has 4 and gates in it.
The and gate can be realised by the electronic circuit by using two ideal p n junction diodes d1 and d2 as shown in fig. The transistors used in this tutorial are bc547 npn transistor and were added with all the above mentioned components in the circuit as shown below. Then the transistors q1 and q2 are off but transistor q3 remains in on and the voltage at the output is low or 0v because of q3 on and current pass through q3 and voltage is dropped through r.
