The Vcc and ground should be applied carefully at the specified pin only.Ĭonclusion We have learned the Implementation of OR Gate using NAND gate.The connections should be tight on trainer kit.Make the connections according to the IC pin diagram.That's why the NAND gate symbol is represented like that. NAND gate operation is same as that of AND gate followed by an inverter. "If either A or B are NOT true, then Y is true" If additional inputs are required, then the standard NAND gates can be cascaded together to provide more inputs. Logic NAND Gates are available using digital circuits to produce the desired logical function and is given a symbol whose shape is that of a standard AND gate with a circle, sometimes called an "inversion bubble" at its output to represent the NOT gate symbol with the logical operation of the NAND gate.Īs with the AND function seen previously, the NAND function can also have any number of individual inputs and commercial available NAND Gate IC's are available in standard 2, 3, or 4 input types. NAND gate - It is a digital circuit that has two or more inputs and produces an output, which is the inversion of logical AND of all those inputs. This OR gate produces an output Y, which is the logical OR of two inputs A, B. "If either A or B is true, then Y is true" Additional inputs will require gates to be cascaded together to obtain the required output value
However, commercial available OR gates are available in 2, 3, or 4 inputs types. Like the AND gate, the OR function can have any number of individual inputs. Logic OR Gates are available using digital circuits to produce the desired logical function and is given a symbol whose shape represents the logical operation of the OR gate. This logical OR is represented with the symbol ‘+’ OR GATE - It is a digital circuit that has two or more inputs and produces an output,which is the logical OR of all those inputs. Power Off Trainer Kit, disconnect all the wire connections and remove IC's from IC-Base.Note down the corresponding output readings for various combinations of inputs.Apply various combinations of inputs according to the truth table and observe the condition of LEDs.Connect the outputs to the switches of O/P LEDs.Connect the inputs to the input switches provided in the IC Trainer Kit.Implement the circuit as shown in the circuit diagram.Connect VCC and ground to respective pins of IC Trainer Kit.Implementation of OR Gate using NAND gate.IC Used For Implementation of OR Gate using NAND gate: IC Number To understand key elements of TTL logic specification or datasheets.To develop digital circuit building and troubleshooting skills.To apply knowledge of the fundamental gates to create truth tables.To understand the behavior and demonstrate Implementation of OR Gate using NAND gate.
