Circuit Diagram Of And Gate. If any inputs are off or at a logic state of 0 the output is off. X or gate assumes logic 1 state when any of its two inputs assumes a logic 1 state.
X or gate assumes logic 1 state when any of its two inputs assumes a logic 1 state. And gate ak digital electronics circuit men use hone bala circuit he iska upyog digital components banane ke liye kiya jata he ap jitne bhi gates ke bare men padenge to un ko acche se samach len kyu ki gates he electronics circuit ke main circuits he inke binka kisi bhi microprocessor ya any upkaran ko nahi banaya ja sakta he. Here we are going to use ic 74ls09 for demonstration this chip has 4 and gates in it.
When both the inputs assume the logic 0 state or when both the inputs assume the logic 1 state the output assumes a logic 0 state.
The below diagram represents the above explained circuit to build an and gate using npn transistor. Let s look at the or gate s truth diagram. An and gate is a logic circuit that only turns on an output when all the inputs are high or a logic state of 1. 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.
